Methyl pepper based epoxy ethyl propionate is insoluble in water and soluble in organic solvents such as ethanol and benzene. Methyl piperonyl epoxypropionate ethyl ester is an important synthetic intermediate that can be used to synthesize various drugs and fragrances.

It is mainly used as a raw material in the synthesis of spices and drugs, for synthesizing compounds such as piperonylacetone and ethyl cinnamate. These compounds have wide applications in fields such as spices, food additives, pharmaceuticals, and pesticides.

The common synthesis methods of PMK ethyl glycidate generally include the following steps:

1. Preparation of raw materials: p - nitrotoluene, epoxy acetone, and ethanol are the main raw materials for synthesizing methyl pepper based epoxy propionate. These raw materials should have high purity and good stability to ensure the quality and yield of the final product.

2. Esterification reaction of p - nitrotoluene with ethanol: Under the action of an acidic catalyst, p - nitrotoluene undergoes esterification reaction with ethanol to produce ethyl methylpiperonate. This reaction is a typical esterification reaction, where carboxyl groups form ester bonds with alcohol hydroxyl groups.

C₆H₅ - NO₂  + CH₃CH₂OH → C₆H₅ - COOCH₂CH₃  + HNO₂

3. The epoxidation reaction of methyl ethyl piperonate: Under the action of an alkaline catalyst, methyl ethyl piperonate undergoes an epoxidation reaction with epoxy acetone to produce methyl piperonyl epoxy propionate. This reaction is a typical epoxidation reaction, in which oxygen atoms are transferred from epoxy acetone to methyl piperonate ethyl ester, forming a new cyclic compound.

(C₆H₅COOCH₂CH₃) + C₃H₄O → C₆H₅COOCH₂CH₂CH₃ + H₂O

4. Separation and purification: By vacuum distillation and crystallization technology, the generated methyl piperonyl epoxy propionate ethyl ester is separated from the mixture. These technologies can remove unreacted raw materials and by - products, improve product purity and yield.

The above is a brief overview of the synthesis of methyl piperonyl epoxy propionate ethyl ester. It should be noted that in actual operation, specific experimental conditions, equipment, safety measures, and other factors need to be considered to ensure the smooth progress of the experiment and the quality and safety of the product.
