    Abstract: Disclosed is an alkanol-free alkoxylate of general formula CnH2n+1O(A)x(B)yR , wherein R represents C1-6 alkyl or benzyl, A represents ethyleneoxy, B represents C3-6 alkyleneoxy or mixtures thereof, groups A and B being provid ed in a statistically distributed fashion, alternatingly, or in the form of two or several blocks in random order, n represents an integer ranging from 4 to 8, x represents a number ranging from 0 to 25, and y represents a number ranging from 0 to 10, the sum of x + y being at least 3.

    Abstract: The production of quaternary glycine nitriles (I) in which R1 and R2 may be the same or different and are an aliphatic, cycloaliphatic or araliphatic radical with 1 to 30 C atoms, whereby R1 and R2 may also form a saturated or unsaturated five or six-member heterocyclic ring together with the N atom to which they are bonded, which can also contain further hetero-atoms, be benzanellated and have alkyl side groups, while R2 may also be hydrogen; R3 is C1 to C4 alkyl or benzyl; R4 is hydrogen, C1 to C20 alkyl which may be interrupted by one or more non adjacent oxygen atoms, or a radical (a) in which R5 is a chemical bond or a C1 to C6 alkylene bridge and XO is a counterion; by the reaction of amines (II) in which the variables R1 and R2 have the above meanings, with a monoaldehyde (IIIa) R6-CHO or a dialdehyde (IIIb) OHC-R5-CHO in which R5 has the above meaning and R6 is hydrogen or C1 to C20 alkyl and hydrocyanic acid or an alkaline metal cyanide in an aqueous medium, followed by quaternation with an alkylation agent (IV) R3-X in which R3 has the above meaning and X is an initial group, by reacting the amines (II) with the aldehydes (III) and hydrocyanic acid or alkaline metal cyanide and quaternising in succession without isolating an intermediate product in an aqueous medium.

    Abstract: A process for the prodn. of (1-4C alkyl) (meth)acrylate esters (AM/AE) from esters of formula (I) and opt. esters of formula (II), in which R = H or Me; R , R = 1-4C alkyl; n = 0 or more. The process comprises reaction in the liq. phase under reduced pressure in presence of acid, with continuous removal of cleavage prods. Also claimed is a process for the prodn. of (AM/AE) by the acid-catalysed esterification of 1-4C alkanols with (meth)acrylic acid, in which by-prods. (I) and (II) are sepd. from the prod. mixt. and subjected to the above cleavage process, and the cleavage prods. are continuously removed and returned to the esterification process.
