Production of hydroxyethyl ethers of butyne-2-diol-1,4
Abstract
Abstract IN WHICH X IS ONE OF THE INTEGERS 1 TO 3, BY REACTING PURIFIED BUTUNE-2-DIOL-1,4 WITH ETHYLENE OXIDE IN THE PRESENCE OF BASIFYING AGENTS, THE IMPROVEMENT WHICH COMPRISES CARRYING OUT THE REACTION BY CHARGING THE BUTYNE-DIOL INTO AN AUTOCLAVE TOGETHER WITH A BASIC ION EXCHANGER RESIN AS BASIFYING AGENT AND FEEDING ETHYLENE OXIDE CONTINOUSLU TO THE AUTOCLAVE FOR FROM 8 TO 16 HOURS AT A REACTION TEMPERATURE OF RROM 45* TO 60*C. THE REACTION MIXTURE THEN BEING LEFT TO STAND AT SAID TEMPERATURE UNTIL THE PRESSURE REMAINS CONSTANT SAID ION EXCHANGER RESIN BEIN A PARTIALLY CROSSLINKED ORGANIC POLYMER BASED ON POLYSTYRENE AND DIVINYL BENZENE AS CROSS-LINKING COMPONENTS SAID POLYMER CARRYING NITROGEN-CONTAINING GROUPS OF THE FORMULAE -N(+)(-R)(-R'')-R", -N(+)(-R)(-R'')- OR >N(+)(-R)- IN THE MACROMOLECULE, IN WHICH R, R'' AND R" DENOTE METHYL OR B-HYDROXYLETHYL, THE FREE VALENCES BEING ATTACHED TO THE MACROMOLECULE THROUGH CARBON ATOMS. 1. IN A PROCESS FOR THE PRODUCTION OF HYDROXYETHYL ETHERS OF BUTYNE-2-DIOL-1,4 OF THE FORMULA HO(H4C2O)X-H2C-C=C-CH2-(OCH2H4)XOH,
