Trimethylolpropane medium-chain ester as well as preparation method and application thereof

Номер: CN115925540A
Принадлежит:

The invention belongs to the technical field of chemical synthesis, and particularly relates to trimethylolpropane medium-chain ester as well as a preparation method and application thereof. The preparation method of the trimethylolpropane medium-chain ester comprises the following steps: mixing trimethylolpropane and C8-C10 medium-chain fatty acid, and carrying out esterification reaction to obtain the trimethylolpropane medium-chain ester, the esterification reaction is carried out in two stages: in the first stage, the temperature is raised to 90-100 DEG C under normal pressure, and the temperature is kept for 50-70 minutes; in the second stage, the pressure is reduced to-0.090 MPa to-0.098 MPa, and the pressure is kept for 5-10 h. The esterification reaction is carried out in two stages, the first stage is mainly degassing, and residual oxygen, moisture and the like in the raw materials are prevented from influencing the reaction; water in the reaction process can be discharged in time ...
