Title:
METHYLENE CHLORIDE SOLUTION OF 3-PENTADECYLPHENOL, PROCESS FOR PRODUCING SAME, AND PROCESS FOR PRODUCING POLYCARBONATE RESIN USING SAID SOLUTION
Document Type and Number:
WIPO Patent Application WO/2015/147198
Kind Code:
A1
Abstract:
Provided are: a process for efficiently producing a methylene chloride solution of 3-pentadecylphenol, which is used as a chain terminator (molecular-weight regulator) for polycarbonate resins, and a process for efficiently producing a polycarbonate resin with excellent moldability by using the solution.
The process for producing a methylene chloride solution of 3-pentadecylphenol comprises introducing a given amount of 3-pentadecylphenol into a dissolution tank for obtaining the methylene chloride solution of 3-pentadecylphenol, through the inlet of the dissolution tank, subsequently closing the inlet, then introducing a given amount of methylene chloride through a methylene chloride introduction line, and stirring the mixture to thereby produce the solution.
