    摘要: Lower alkyl esters of higher fatty acids with improved processing properties, particularly sulfonation, are obtained by subjecting lower alkyl esters of higher fatty acids of plant and/or animal origin, or said fatty acids per se, in the presence of esterification catalysts and/or carboxylic acid anhydrides, to a brief temperature treatment above 150.degree. C., and separating simultaneously and/or subsequently, preferably by distillation, the purified lower alkyl esters of higher fatty acids or the purified higher fatty acids from the treated material and the purified higher fatty acids are then esterified with lower alkanols.

    摘要: A drying cylinder adapted to receive steam therein includes a cylindrical cylinder jacket and two end covers. There is a flange connection between the jacket and the covers. The jacket has a rectangular cross-section flange. The covers have an L-shaped flange which receives the end flange of the cover. The covers are concave to the outside of the cylinder. The point of intersection of a curved line through the cover and of the axial center line of the axial arm of the cover flange lies at a distance from the outer face of the flange of the end cover that is at most about 60% of the axial length of the axial arm of that flange. There is thermal insulation on the axially exterior side of each cover.

    摘要: A process for the production of a mixed formal of polyglycol ethers having formulae selected from the group consisting of ##STR1## wherein R.sup.1 is a straight or branched chain alkyl having from 1 to 18 carbon atoms, and R.sup.2 is selected from the group consisting of hydrogen and straight or branched chain alkyl having from 1 to 17 carbon atoms, where the sum of the carbon atoms in R.sup.1 plus R.sup.2 is from 6 to 18, R.sup.3 is a member selected from the group consisting of monoalkylphenyl having from 14 to 26 carbon atoms, dialkylphenyl having from 14 to 26 carbon atoms, trialkylphenyl having from 14 to 26 carbon atoms, a straight or branched chain alkyl having from 8 to 22 carbon atoms, a straight or branched chain alkenyl having from 8 to 22 carbon atoms, and a radical having the formula ##STR2## wherein R.sup.1 and R.sup.2 have the above assigned values, and R.sup.5 is selected from the group consisting of a straight or branched chain alkyl having from 1 to 5 carbon atoms, phenyl and alkylphenyl having from 7 to 9 carbon atoms, R.sup.4 is a straight or branched chain alkyl having from 1 to 5 carbon atoms, A and B are selected from the group consisting of ethylene and isopropylene, m and n are integers from 0 to 50, p is an integer from 2 to 50, and q is an integer from 0 to 3, where the sum of m plus n is from 2 to 50, consisting essentially of the steps of(1) reacting a polyglycol ether having the formulae selected from the group consisting of ##STR3## wherein R.sup.1, R.sup.2, R.sup.3, A, m, n and p have the above-assigned meanings, with a diformal having the formulaR.sup.4 --O--(B--O).sub.q --CH.sub.2 --(O--B).sub.q --O--R.sup.4wherein R.sup.4, B and q have the above-assigned meanings, at a temperature of from 60.degree. to 150.degree.
