Abstract
PURPOSE: To prepare the title compound useful as an epoxy resin hardener and a raw material of polyester, in high yield, by reacting olefins composed mainly of 2,4, 4-trimethylpentene-1 with maleic anhydride in the presence of naphthol.
CONSTITUTION: The title compound is prepared by reacting olefins composed mainly of 2,4,4-trimethylpentene-1 (pref. ≥50mol%) with maleic anhydride in the presence of ≥0.01wt% (pref. 0.05W1wt%) based on the maleic anhydride, of naphthol, at 150W250°C, pref. 180W220°C. The molar ratio of 2,4,4,-trimethylpentene-1 to maleic anhydride is 1.7W15 (pref. 2W10) in view of the selectivity, the color development of the product, and the cost.
USE: Raw material of alkyd resins, plasticizers, surface active agents, etc.
