Abstract: The present invention relates to novel mixtures of (meth)acrylic esters of polyalkoxylated trimethylolpropane of the formula where AO is for each AO independently at each instance EO, PO or BO where EO is O-CH2-CH2- PO is independently at each instance O-CH2-CH(CH3)- or O-CH(CH3)-CH2- BO is independently at each instance O-CH2-CH(CH2-CH3)- or O-CH(CH2-CH3)-CH2- p1+p2+p3 is 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74 or 75, R1, R2 and R3 are independently H or CH3, a simplified process for preparing these ester mixtures and the use of reaction mixtures thus obtainable.

Abstract: Basic (meth)acrylates IV are prepared by transesterification of alkyl (meth)acrylates I in the presence of a catalyst and working-up of the reaction mixture by distillation, by a process in which a gas or gas mixture which is inert under the reaction conditions is passed through the reaction zone and/or heat exchanger.

Abstract: The base (1) for a column to rectify or absorb thermally unstable materials, which tend to polymerize, has risers (7) with covering hoods (8) supported on struts (9). Collected liquid can also run off the edge of the base through outflows (6) from one or more gutters (5). The gutters are angled downwards towards the edge of the base by 0.2-5.0[deg] and preferably 0.5-2.0[deg], and the base surface is angled down towards the gutters by 0.5-5.0[deg] and preferably 1-3[deg]. The under side (2) of the base is flat and horizontal.

Abstract: A process for rectificatively separating at least one (meth)acrylic monomer-containing fluid by feeding the fluid into a rectification column containing at least one sieve tray without a runoff segment, wherein an elementary cell is obtained from a number of centers of passages in a sieve tray, and the cell shifts regularly and repeatedly along its edges, the lengths of two shifting vectors being the lengths of the edges of the cell along which the shifting is effected; an arrangement of the centers is such that the positions of an ideal center and a real center are separated by
