    摘要： A low-formaldehyde binder consists essentially of(A) from 5 to 80% by weight of a water-soluble condensation product of carbonyl number 0-200 which has been prepared by alkaline condensation from 0.1 to 0.4 mole of an aliphatic or cycloaliphatic condensable ketone and 1 mole of formaldehyde, and(B) from 20 to 95% by weight of 4,5-dihydroxyimidazolidin-2-one and/or an unetherified, partially etherified or completely etherified condensation product thereof with an aliphatic monoaldehyde or dialdehyde.

    摘要： Alkylglucosides are prepared by acetalization of glucose with an equivalent amount or an excess of a C.sub.3 -C.sub.5 -alkanol in the presence of an acidic catalyst by a method wherein the acetalization is carried out in the presence of an alkali metal salt of a boric acid used in an amount which is equivalent to or in excess of the amount of the catalyst.The alkylglucosides obtained can be used directly, for example as solubilizers, in particular in the cosmetic sector, or can be reacted further to give higher alkylglucosides.

    摘要： A process for the preparation of curable etherified aminoplast resins based on urea/aldehyde polycondensates, and the preparation of surface coating resins.Urea is first reacted with an .alpha.,.alpha.-dialkylaldehyde, as much as 50 mol % of which may be replaced by formaldehyde, in a molar ratio urea/aldehyde of about 1:2, at from 50.degree. to 120.degree. C., in the presence of an acid and in the presence or absence of an alcohol or of other organic solvents, and the 2-oxohexahydropyrimidine derivative obtained in this cyclocondensation is then condensed with formaldehyde in the presence of one or more alcohols and an acid.These aminoplast resins are useful as both acid-curable resins and as resins for baking finishes.
