SOLVENT AND A METHOD FOR PRODUCTION THEREOF Russian patent published in 2002 - IPC

Abstract RU 2180679 C2

FIELD: petrochemical processes. SUBSTANCE: invention relates to solvent containing straight-run distillate isolated from polymerizate in the course of petroleum polymer resin production involving condensation reaction. In particular, straight-run distillate, containing, wt %: styrene 0.05-0.5, xylenes 1.7-4.7, alkylbenzenes 11.5-20.6, alkylstyrenes 12.5-18.9, dicyclopentadene + aromatic hydrocarbons C9H10 12.7- 18.5, indene 2.5-4.0, naphthalene 3.5-9.0, and nonaromatic hydrocarbons to 100%, is subjected to hydrofining on nickel/kieselgur catalyst at 80 to 140 C. EFFECT: reduced power consumption and improved quality of product enabling production of solvent for varnish-and-paint materials with good consumer's properties. 3 cl, 1 tbl, 3 ex
