Catalytic metal oxide preparation of polyetherols, useful as fuel additives, surfactants, in paints, as emulsifying and dispersing agents and in polyurethane synthesis, by reaction of alkylene oxide with starter compound

摘要

A process for preparation of polyetherols includes reaction of at least one alkylene oxide with at least one starter compound in the presence of a catalyst which is a multimetal oxide compound. A process for preparation of polyetherols includes reaction of at least one alkylene oxide with at least one starter compound in the presence of a catalyst, i.e. a multimetal oxide compound of formula (I). M1p(M2qOn(OH)2(3-n))x (I) M1 = at least 1 element from the groups IA, IIA, IIIA, IVA, VA, IB, IIB, IIIB, IVB, VB, VIB, VIIB and/or VIIIB; M2 = at least one element from groups IVA, VA and/or VIA, n = 2 or 3, p = 0 or fractional or whole number greater than 0, q = fractional or whole number greater than 0, x = 1-20 fractional or whole number. An Independent claim is included for a polyetherol obtained as above.
