Problems solved by technology

It is derived from petroleum and cannot be degraded in the soil for a long time after use, causing environmental pollution and does not meet the current environmental protection requirements
Moreover, as the price of oil continues to rise, the price of diluents will rise accordingly, which will make it difficult to control the production cost of pesticides and fungicides and the cost of using them in agriculture.

Abstract

The invention discloses a production method of isopropyl myristate, which includes four steps. Firstly, myristic acid (tetradecanoic acid) is added with isopropanol and catalyzer TiO2 for esterification; secondly, the esterified product is dealcoholized; thirdly, the catalyzer is recovered; fourthly, the recovered catalyzer product is rectified, and therefore the isopropyl myristate of the invention is produced. The isopropyl myristate of the invention has the advantages of innocuity, no causticity, easy emulsification, easy degradation, environmental protection and safe storage and transporation. The isopropyl myristate of the invention can not only be applied to cosmetic and daily chemical industries but also be used as the solvent of pyrethrins insecticides.

Description

technical field [0001] The invention relates to a production method of isopropyl myristate. Background technique [0002] Among the pyrethroid insecticides, the proportion of emulsifiable concentrate formulations is very large. The diluents used in the emulsifiable concentrate solvent are mainly toluene and xylene, which can account for more than 80% of the total content of the emulsifiable concentrate preparation. It has an anesthetic effect on the central nervous system and a stimulating effect on the mucous membrane. People who are poisoned may experience headaches, dizziness, and excitement. Or drunkenness, drowsiness, etc. In severe cases, convulsions and coma will also occur. It is derived from petroleum, and cannot be degraded in the soil for a long time after use, causing environmental pollution, which does not meet the current environmental protection requirements. Moreover, as the oil price continues to rise, the price of the diluent rises thereupon, thereby caus...
