Process of producing mono and polyhydroxyl ethers

Abstract

Abstract 1. A PROCESS FOR PREPARING A MEMBER SELECTED FROM THE GROUP CONSISTING OF POLYHYDROXYL EHTER AND POLYHYDROXYL POLYETHER CONSISTING ESSENTIALLY OF (A) HEATING AT A TEMPERATURE BETWEEN 50-1200*C. A CORRESPONDING ETHER SELECTED FROM THE GROUP CONSISTING OF MONOETHER AND POLYETHER, CONTAINING AT LEAST ONE OXYALKYLENE RADICAL HAVING A FORMULA SELECTED FROM THE GROUP CONSISTING OF -(CH2-CH(-CH2-O-C(-CH3)3)-O)- AND -(CH(-CH2-O-C(-CH3)3- CH2-O)- SAID CORRESPONDING ETHER BEING PRODUCED BY REACTING TERIOBUTY GLYCIDLY ETHER AND A COMPOUND OF THE FORMULA R (XH)A WHEREIN A IS AN INTEGER OF 1-6 R IS ALKYL HAVING 1-30 CARBON ATOMS AND X IS 0, THE PROPORTION OF SAID TERTIOBUTY GLYCIDYL ETHER TO SAID COMPOUND EXPRESSED IN MOLES OF EPOXIDE PER GRAM ATOM OF REACTIVE HYDROGEN BEING 0.1-10, AT A TEMPERATURE OF 80-180* V. IN THE PRESENCE OF A BASIC CATALYST SELECTED FROM THE GROUP CONSISTING OF ALKALI METAL AND THE HYDROXIDE, ALCOHOLATE AND MERCAPTIDE THEREOF, PRESENT IN AMOUNTS OF 0.1-1 PERCENT BY WEIGHT OF THE REACTION MASS, THE HEATING OF SAID CORRESPONDING ETHER BEING CARRIED OUT IN PRESENCE OF A CATALYST SELECTED FROM THE GROUP CONSISTING OF BENZENE SULFONIC ACID, PARTATOLUENE SULFONIC ACID, SULFOSALICYLIC ACIDS, 3-HYDROXY PROPANE SULFONIC ACID, SULFOAIETIC ACID, A SULFOLAURIC ACID, A SULFOPALMITIC ACID AND A-SULFOSTEATIC ACID, SAID CATALYST BEING PRESENT IN AMOUNTS OF ABOUT 0.5-20 PERCENT BY WEIGHT OF SAID CORRESPONDING ETHER; AND (B) A PROSGRESSIVELY ADDING WATER TO SAID CORRESPONDING ETHER AND SAID CATALYST BEING HEATED, IN AMOUNTS OF 10-200 PERCENT BY WEIGHT OF SAID CORESPONDING ETHER,
