Abstract

1,164,997. Acetals of polyether polyols. B.P. CHEMICALS (U.K.) Ltd. 17 Nov., 1966 [25 Nov., 1965], No. 50126/65. Heading C2C. [Also in Division C3] Novel polyether polyols having a functionality of at least 4 and containing at least 1 but not more than 3 acetal links between branch points in the molecule are prepared by reaction of a polyether polyol having a functionality of at least 3 and an aldehyde under acidic conditions, whereby at least 0À5 but not more than 0À75 mole of aldehyde reacts for each mole of polyol present. The invention also comprises novel mixtures of polyether polyols having an average functionality greater than 3, at least one of the polyether polyols in the mixture having a functionality of at least 4 and containing 1 or more acetal links between branch points in its molecule, and the mixture as a whole containing an average of not more than 3 acetal links per molecule, which are prepared by reaction under acidic conditions of a polyether polyol having a functionality of at least 3, a mixture of polyether polyols or a mixture of one or more polyether polyols with a polyol which is not a polyether polyol but which contains at least 4 carbon atoms between any 2 of its hydroxyl groups, any such mixture having an average functionality greater than 2À25 whereby not more than 0À75 mole of the aldehyde reacts for each mole of polyol initially present, but sufficient aldehyde reacts to raise the functionality of the mixture to more than 3. Suitable polyether polyols for use as starting materials are the condensation products of ethylene oxide and/or 1,2-propylene oxide with glycerol, trimethylolpropane, 1,3,5-trihydroxycyclohexane, pentaerythritrol, sorbitol and sucrose, and mixtures thereof with each other and with polyoxyalkylene glycols. Suitable polyols which are not polyether polyols are diethylene and dipropylene glycols, tetramethylene and pentamethylene glycols, 1,4- dihydroxy- and dimethylol-cyclohexanes and bis-(2-hydroxyalkyl)-ethers of dihydroxy aromatic compounds. Specified aldehydes are aliphatic aldehydes containing up to 4 carbon atoms, especially formaldehyde, and also benzaldehyde and glyoxal. The resulting polyether polyols preferably have hydroxyl numbers between 30 and 70 mg. KOH per gram and may be reacted with ethylene oxide and/or propylene oxide to reduce the hydroxyl numbers to this range.
