Title: Polyether poly:ol(s) prodn. - by reacting poly:hydroxy cpd. with alkylene oxide in aq. emulsion and sepg. prod. in fibre bed
IPC: C08G18/48
Filed: 1983-02-16
Abstract: Polyetherpolyols are made by reacting a polyhydroxy cpd. with one or more alkylene oxides in the presence of an alkaline catalyst, the reaction mixt. being in the form of an aq. emulsion. After the oxyalkylation reaction, the reaction mixt. is neutralised and passed through one or more fibre beds to cause phase separation and the polyol phase is freed from or virtually completely freed from the water present. Pref. the fibre beds are of glass fibre or are made by sintering stainless steel fibres. Each fibre bed is pref. 2-4 cm thick, and two or more fibre beds are combined to form an exchangeable sepn. element. Pref. the reaction mixt. is neutralised with HePO4 the catalyst used for the oxyalkylation is KOH, and after the first phase sepn. the water still present in the polyol phase is largely removed by evapn., the phosphate which crystallises out is filtered off, and the residual water is removed. Prods. are esp. useful for the prodn. of polyurethanes. Process is less time consuming than prior art processes, gives alkali-free polyol, and does not require the use of organic solvents.
