| titleOfInvention | Preparation method for dimethyl sebacate |
| abstract | The invention belongs to the field of chemical product preparation and particularly relates to a preparation method for dimethyl sebacate. A production method for the dimethyl sebacate comprises the following steps of esterification reaction and rectification process and has the concrete steps that: sebacic acid is mixed with methanol, then, solid catalysts are added, the esterification reaction is carried out, and then, products are purified through a rectification process. The method has the beneficial effect that the consumption mol ratio of the sebacic acid to the methanol is 1/0.9 to 1.2. Compared with the prior art, the method has the advantages that the consumption of the methanol is greatly saved, about 3 percent of the cost is saved, the solid acid is used as catalysts, the reaction efficiency is greatly improved, in addition, compared with the prior art adopting concentrated sulfuric acid as catalysts, the method has the advantage that the solid catalysts adopted by the method can be cyclically utilized, and compared with the method adopting liquid catalysts, the method has the advantage that about 5 percent of the cost is saved. |
