Abstract

The invention relates to the technical field of initiators, in particular to peroxided neodecanoic acid isopropyl phenyl ester and a method for preparing the peroxided neodecanoic acid isopropyl phenyl ester through a phase transfer catalyst. The method for preparing the peroxided neodecanoic acid isopropyl phenyl ester comprises the steps that 1, cumyl hydroperoxide and potassium hydroxide are subjected to a reaction; 2, the phase transfer catalyst is added; 3, neodecanoyl chloride is added dropwisely; 4, standing is performed for layering, and mother solution separation is performed; 5 washing is performed. The phase transfer catalyst is added in the process of preparing the peroxided neodecanoic acid isopropyl phenyl ester, a mother solution is layered more easily, and mother solution separation is more easily achieved; furthermore, after the phase transfer catalyst is added, the quality of the obtained peroxided neodecanoic acid isopropyl phenyl ester is better; in addition, the yield of the peroxided neodecanoic acid isopropyl phenyl ester is improved, and the technology for preparing the peroxided neodecanoic acid isopropyl phenyl ester is high in efficiency and yield.

Description

technical field [0001] The invention relates to the technical field of initiators, and relates to a method for preparing cumyl peroxyneodecanoate and a phase transfer catalyst. Background technique [0002] With the rapid development of the domestic polymer synthesis industry, the variety and demand of initiators for polymer synthesis have increased rapidly. Cumyl peroxyneodecanoate, as a high-efficiency initiator for polymer synthesis, compared with other types of initiators, has the advantages of less solvent-based initiator consumption, The advantages of high initiation efficiency, uniform exothermic polymerization reaction, and easy control, such as the Chinese patent document with publication number 102532351A, which discloses a method for preparing cumyl peroxyneodecanoate with an emulsion-type mass fraction of 50% , but in the preparation process of this patent, because the density of the mother liquor is close to that of water, the mother liquor is not easy to separ...
