There are various methods for preparing 4- (cyanomethyl) -1,3-dioxyamyl-2-one. Common ones include the following:
First, formaldehyde, glycolic acid and hydrocyanic acid are used as raw materials. First, formaldehyde and glycolic acid are condensed under appropriate conditions to form corresponding hydroxyl esters, and then nucleophilic addition reaction occurs with hydrocyanic acid to obtain the target product precursor. After cyclization and other steps, 4- (cyanomethyl) -1,3-dioxyamyl-2-one can be prepared. This process requires attention to the control of reaction conditions, such as temperature, pH, etc., to ensure the smooth progress of the reaction. < Br >
Second, glyoxal and ethyl cyanoacetate are used as starting materials. The two first condense to form an intermediate with a certain structure, and then through a series of reactions such as hydrolysis and cyclization to achieve the synthesis of the target product. In this path, the hydrolysis and cyclization steps are quite critical, and the reaction reagents and conditions need to be carefully selected to improve the yield and purity of the product.
Third, vinyl carbonate can also be used to react with sodium cyanide (or other cyanide sources). Vinyl carbonate has an active ring structure. In the presence of a suitable catalyst, nucleophilic substitution reactions occur with cyanogen sources, and cyanogen methyl can be introduced to construct the structure of 4- (cyanomethyl) -1,3-dioxolane-2-one. The choice and dosage of catalysts have a great impact on the reaction rate and selectivity, and need to be carefully considered.
The above methods have their own advantages and disadvantages. In actual synthesis, it is necessary to comprehensively weigh factors such as the availability of raw materials, the difficulty of controlling reaction conditions, and cost, and choose the best one.

4 - (cyanomethyl) -1,3 -dioxane cycloacetic anhydride should be paid attention to when it is stored and transported.
First, because of its chemical activity, it is easy to react with other substances, so it is necessary to keep away from oxidants, acids and alkalis. If it touches it, it may react violently, causing fire and explosion. Such as the ancient armor, each has its own genus. If it is placed in a mixed manner, it is prone to disasters.
Second, this product is mostly corrosive and can erode skin and utensils. When storing and transporting, use a corrosion-resistant container and pack it tightly. During the handling process, the operator must wear protective clothing, protective gloves and goggles, just like wearing armor to prevent accidental contamination and injury to himself.
Third, temperature and humidity have a great impact on its stability. It should be stored in a cool, dry and well-ventilated place, away from direct sunlight, just like choosing a quiet and dry treasure to prevent it from being damaged by changes in temperature and humidity.
Fourth, the storage and transportation site should be equipped with corresponding fire protection and leakage emergency treatment equipment. Once something happens, it can be responded quickly, such as in a battle area, always have weapons to defend against the enemy immediately.
Finally, the relevant operation and management personnel, when familiar with the characteristics of this object and safety precautions, after professional training, are allowed to take up the post, just like before the march, soldiers must know the art of war before they can respond to the enemy.
