Abstract: The dyeing or printing of fibrous materials is improved by using a compound of the formula R1-CHX-(CH2-CH2-O)n-R2 in which R1 is alkyl of four to 20 carbon atoms, X is chlorine or bromine, n is a number of three to about 200 and R2 is an aliphatic hydrocarbon radical of up to 20 carbon atoms, alkylphenyl with up to 12 carbon atoms in the alkyl moiety, phenyl, naphthyl, benzyl, the acyl residue of a fatty acid of up to 18 carbon atoms, benzoyl or the group of the formula R1-CHXCH2-CH2, as dispersing, levelling or after treating agent. The improvement consists in the combination of dispersing and levelling properties.

Abstract: Process for the preparation of 1,4-naphthodinitrile, by reacting o-phenylene-diacetonitrile with a glyoxalbisaldimine. By this process the 1,4-naphthodinitrile is easily obtained in a one-step process. This compound is an important intermediate for the production of 1,4-naphthalene-dicarboxylic acid.

Abstract: Process for the preparation of trans, trans-muconic acid by reacting a glyoxalacetal with ketene in the presence of an acid catalyst and hydrolyzing the beta , beta '-dialkoxy-adipic acid-alkylester formed with alkali. By this new process trans, trans-muconic acid is easily obtained in better yield, which compound is an important intermediate for the production of 1,4-naphthalene-dicarboxylic acid esters.
