VERFAHREN ZUR HERSTELLUNG VON GLYCIDYLESTERN UND DEREN VERWENDUNG ALS KLEBSTOFFE IN DER ELEKTRONIKINDUSTRIE
摘要
Glycidyl esters are prepared to have low chlorine, chloride, sodium and potassium contamination and a thixotropic index greater than 3.0 by a process that comprises reacting carboxylic mono- or dimer acids with glycidyl alcohols in a molar ratio of 1 to (0.9-4.0) using carbodiimide as the acylating agent and a pyridine-type catalyst. The pyridine-type catalyst is removed by strongly acidic ion exchange resin.
