Appropriate application can regulate the growth and development process of plants, such as promoting seed germination and enhancing plant stress resistance. It can affect the hormone balance in plants, make crops better adapt to environmental changes, improve crop yield and quality, and help agricultural production.

Methyl itself is not a common optical substance. It is speculated that what you call "methyl benzene", which is generally benzene, is an organic compound. Its optical properties can be viewed from the following aspects:
First, in terms of refractive index, toluene has a specific refractive index. Under standard conditions, the refractive index is about 1.4967. This value reflects the degree to which the propagation direction changes when light is emitted from air to toluene. When light is incident obliquely into toluene from air, due to the difference in refractive index between the two, the light will be refracted. According to the law of refraction, the ratio of the refractive angle to the sine of the incident angle is equal to the relative refractive index of toluene to air, which is closely related to the molecular structure and density of toluene.
Second, in terms of light transmittance, toluene has good light transmittance in the visible light band, showing a colorless and transparent shape, allowing visible light to pass through. However, in the ultraviolet light band, due to the electron transition characteristics of toluene molecules, it absorbs ultraviolet light of specific wavelengths, and its absorption spectrum has a characteristic absorption peak, which is related to the conjugated system of benzene rings in the molecule, and π electrons absorb corresponding energy photons between different energy levels.
Third, in terms of optical rotation, the molecular structure of toluene has no chiral center, no optical rotation, and cannot rotate the vibration plane of polarized light. Because its molecules have a symmetrical structure, there is no special spatial arrangement that can rotate polarized light.
Fourth, in terms of scattering characteristics, when light passes through a system containing toluene, such as a mixed system of toluene and other particles, light scattering occurs. The degree of scattering is related to the concentration of toluene, the size of the particles, and the wavelength of the light. According to Rayleigh's scattering law, when the particle size is much smaller than the wavelength of light, the intensity of scattered light is inversely proportional to the fourth power of the wavelength of light.

A basic light has unique chemical properties, which is quite important to the Alchemy family. A basic light has flammability. Before the open flame, it is easy to rise to flames, the flame color is blue, and the burning speed is quite fast, and it can burn out in the process. This combustion is also often accompanied by the release of heat, which can provide the required energy for various changes.
It is also oxidizing and can be combined with other substances. When encountering active metals, such as the genera of sodium and potassium, it can be combined with them to form different qualities. This process of synthesis is also often accompanied by heat and light, just like the appearance of stars, which is very gorgeous.
It also has additive properties. Under appropriate conditions, it can be added with alkenes and alkynes to make its structure easier and new substances can be formed. This addition change is like the art of a skilled craftsman, causing thousands of changes to the original.
A basic light also has the property of substitution. Under suitable conditions, some of its atoms can be replaced by other atoms or groups to form new compounds. This substitution change is like a game of exchange. Although the atoms are changed, the overall nature also changes.
A basic light is used in organic synthesis and has a wide range of uses. It can be used as a raw material to make various fine chemicals, and can also be used as a reaction medium to help the reaction run smoothly. In today's world, many chemical industries are based on the basic nature of light, creating countless things that are convenient for the people and benefit the people's livelihood.

The method of making cresol square light depends on the selection of materials, processing and heat control.
First of all, the selection of materials must be made of high-quality raw materials. The base material used in cresol square light is selected at a specific time, with pure texture and no impurities. For example, if the wood used needs to be cut from deep mountains and old forests, the age of the trees is appropriate, and the wood is firm; the stone used should be collected from the essence of the veins, the stone is warm and delicate texture. Such raw materials are the foundation for making good tools.
As for processing, the method is complicated. As far as wood is concerned, it is first soaked in the concoction. The formula of the concoction is prepared according to the ancient method. It is fried with several herbs and soaked for several months to nourish the wood, remove its dryness and increase its toughness. Then take it out, put it in a ventilated place and dry it in the shade. When it dries to a moderate extent, it is slightly roasted on a charcoal fire. When roasting, a special person is required to watch the change of its color and texture, until it is the same on the outside, it is qualified. The preparation of the stone needs to be washed with water, and then carefully polished with a special emery cloth to grind off its brown surface to show its luster. Then it is applied with a secret paste and buried in the soil for a few days. After it fuses with the earth gas, it is taken out and then ground. Repeated several times, the texture of the stone is more delicate and radiant.
The control of the heat is particularly critical. When firing cresol square light, the furnace temperature needs to be precisely adjusted according to different stages. Start by drying slowly with a warm fire, so that the inside and outside of the utensils are heated evenly and moisture is forced out. Then it is turned to a fierce fire, and the fire is raging. At this time, it is necessary to pay close attention to the changes in the furnace. The color and shape of the utensils have subtle changes. At this critical time, if the heat is too strong, the utensils will be easy to crack, and if the heat is insufficient, it will be difficult to form. When the utensils show a specific color and texture, turn to a warm fire and simmer to stabilize the properties of the utensils until you are done.
To make cresol square light, select the material as the base, process it as the method, and heat as the soul. The three complement each other, and none of them are indispensable, in order to make excellent cresol square light.

P-aminobenzoic acid is a white to light yellow crystalline powder, and there are many points to be paid attention to in storage and transportation.
When stored, the first environment is dry. Because aminobenzoic acid has certain hygroscopicity, if the environment is humid, it is easy to cause it to get damp and agglomerate, which affects the quality, so it should be placed in a dry and well-ventilated place. Furthermore, avoid light exposure. This substance is sensitive to light, and long-term exposure to light will cause luminescent chemical reactions, causing its structure to change, thereby reducing its purity and activity. It should be stored in dark containers such as brown bottles. Temperature should also be controlled. If it is too high, it may decompose, and if it is too low, it may solidify. Generally, it is appropriate to refrigerate at 2-8 ° C.
During transportation, the packaging must be sturdy. Aminobenzoic acid is a chemical, and suitable packaging materials should be used, such as sealed plastic bags plus strong cartons or iron drums, to prevent package damage and leakage during transportation. At the same time, relevant transportation regulations should be strictly followed. Due to its special nature, transportation needs to be carried out according to the requirements of chemical transportation, and transportation personnel should have professional knowledge and know emergency treatment methods. It is also necessary to avoid mixing with other chemicals. Aminobenzoic acid or reaction with certain substances can easily cause danger. It must be transported separately or with substances with compatible properties. In short, whether it is storing or transporting aminobenzoic acid, its characteristics should be carefully considered and its quality and safety should be ensured.
