摘要： 1. IN PROCESS FOR PREPARING A POLYURETHANE FOAM BY REACTING A POLYETHER POLYOL WITH AN ORGANIC POLYISOCYANATE IN THE PRESENCE OF A REACTION CATALYST AND A FOAMING AGENT, SAID POLYETHER POLYOL COMPRISING THE PRODUCT OF REACTING 4,4,4, - TRICHLORO -1,2- EPOSYBUTANE WITH A MIXTURE OF (1) DEXTROSE AND (2) WATER, A POLYHYDRIC ALIPHATIC ALCOHOL OR A MIXTURE OF WATER AND A POLYHYDRIC ALIPHATIC ALCOHOL, THE IMPROVEMENT WHICH COMPRISES USING SAID EPOXYBUTANE AS A CRUDE MATERIAL HAVING NO MORE THAN ABOUT 5% BY WEIGHT OF VOLATILE COMPONENTS AND CONTAINING FROM ABOUT 15 TO ABOUT ABOUR 42% BY WEIGHT OF IMPURITIES AND CORRESPONDINGLY FROM ABOUT 85 TO ABOUT 58% OF SAID EPOXYBUTANE, SAID CRUDE EPOXYBUTANE BEING PREPARED BY A PROXESS CONSISTING ESSENTIALLY OF (A) REACTING, AT A TEMPERATURE FROM ABOUT 35 TO ABOUT 62* C., 4,4,4-TRICHLORO-2-HALOBUTANOL WITH AN AQUEOUS SOLUTION AF AN ALKALI METAL HYDROXIDE OR AN ALKALINE EARTH METAL HYDROXIDE, SAID AQUEOUS SOLUTION BEING EMPLOYED IN A SUFFICIENT PROPORTION TO PROVIDE AT LEAST A STOICIOMETRIC AMOUNT OF HYDROXIDE WHICH IS REQUIRED TO REACT WITH SAID 4,4,4, - TRICHLORO -2HALOGUTANOL, THEREBY FORMING A TWO-PHASE REACTION PRODUCT MIXTURE, NAMELY, AN AQUEOUS PHASE AND A NON-AQUEOUS PHASE CONTAINING SAID CRUDE EPOXYBUTANE, AND (B) SEPARATING SAID TWO PHASES AND RECOVERING SAID CRUDE EPOXYBUTANE.
