Abstract: An ester mixture of trialkyl esters of cyclohexane-1,2,4-tricarboxylates having isomeric pentyl radicals in which more than 5 mol % of the isomeric pentyl radicals are branched.

Abstract: A mixture of isomeric dipentyl terephthalates, pentyl radicals of which are n-pentyl radicals to an extent of less than 60 mol %, characterized by a low viscosity which does not increase significantly even at temperatures below 40° C. Plastisols comprising these mixtures have a low plastisol viscosity which moreover increases only to a minor degree with time.

Abstract: Tripentyl esters of trimellitic acid, especially mixtures of triisopentyl esters of trimellitic acid comprising isomeric pentyl radicals in which more than 5 mol % of the isomeric pentyl radicals incorporated in the ester mixture are branched, have good compatibility with PVC and PVC-containing polymers and simultaneously exhibit a lesser tendency to migrate.

Abstract: The present invention relates to a method for preparing saturated Cn- and C2n-alcohols, wherein the separation of the Cn-alcohols and the C2n-alcohols is effected by means of at least one two-column system or by means of at least one dividing wall column.

Abstract: The present invention relates to a method for preparing saturated Cn- and C2n-alcohols, wherein the ratio of Cn- to C2n-alcohols is controlled by a distillative separation of the aldehydes used.

Abstract: Ester mixtures comprising the esters A(COOR1)(COOR1)x, A(COOR1)(COOR2)x, A(COOR2)(COOR1)x and A(COOR2)(COOR2)x, can be produced in a targeted way by processes in which acids A(COOH)x+1 or derivatives thereof are reacted with an amount (m1+s1) of R1OH and an amount m2 of R2OH, the reaction mixture being heated at boiling, the alcohol R1OH having a lower boiling point than the alcohol R2OH, A being an aromatic, alicyclic or aliphatic radical, x being 1 or 2, and R1 and R2 independently of one another being substituted or unsubstituted aryl radicals or linear or branched, substituted or unsubstituted alkyl radicals having 3 to 20 carbon atoms, m1 and m2 corresponding to the mole equivalents of the alcohol radicals OR1 and OR2 to be introduced into A(COOH)x+1 or derivatives thereof, and s1 being greater than 0.

Abstract: The present invention relates to a method for preparing saturated Cn- and C2n-alcohols, wherein the ratio of Cn- to C2n-alcohols is controlled by the diversion of substreams in individual method steps.

Abstract: A mixture (1) can be prepared in a controlled manner and used as a plasticizer, the mixture contains an epoxidized fatty acid ester A; and a compound B containing a fatty acid chain and having no functional group including a multiple bond in the fatty acid chain. The proportion by mass of compound B is smaller in said mixture (1) than a proportion of compound B in a mixture (2) of compounds containing a fatty acid chain from which the mixture (1) comprising epoxidized fatty acid ester A has been prepared.

Abstract: A method for the production of cellulose having a low lignin content characterized by a combination of the measures that a) a lignocellulosic material is treated with an aqueous solution comprising a C1-6-alcohol and having a pH from 10 to 14 at a temperature of below 100° C., whereupon the aqueous solution, in which lignin split off from the lignocellulose is present in dissolved form, is separated from the solid which represents a material enriched with cellulose and hemicellulose, b) hemicellulose is removed from the material of a) enriched with cellulose and hemicellulose, c) the material obtained in b), which is hemicellulose depleted, is treated with an alkali sulfite, an alkaline earth sulfite or ammonium sulfite, in particular Na2SO3 and/or with oxygen in aqueous alkaline solution, whereby lignin dissolves and cellulose having a low lignin content is obtained; as well as cellulose which can be produced by the method.
