| titleOfInvention | Preparation method of polyricinoleate |
| abstract | The invention discloses a preparation method of poly-ricinoleic acid ester, which comprises the steps of firstly adding castor oil and alkali liquor into a reaction kettle, starting a heating pipe to heat and stir for reaction, standing and cooling to room temperature, then neutralizing with concentrated sulfuric acid, washing, and separating oil phase to obtain castor oil hydrolysate; then mixing the castor oil hydrolysate, the polyhydric alcohol, the acid anhydride and the acid catalyst, introducing nitrogen to heat for dehydration condensation reaction, thereby preparing the final product of the polyricinoleate. The process has low requirement on the purity of the raw materials, can directly take the castor oil sold in the market as the raw material, and has low cost through simple process treatment; the reaction process conditions are mild, the adopted equipment is simple, the production period is short, the equipment investment and the energy consumption are saved, the production efficiency is improved, the polymerization degree of the prepared polymer can be regulated, the product coverage range is wide, the method can meet the requirements of various metal working fluids, and the market application prospect is wide. |
