Abstract

A detergent composition contains, as an optical brightening agent, a di-[benzimidazolyl-(2)]-ethylene compound of the formula:- <FORM:0880484/III/1> in which m and n represent whole numbers of at most 2, or a sulphate, hydrochloride, acetate or tartrate of such compound. In an example an aqueous slurry of sodium lauryl sulphate, sodium dodecylbenzenesulphonate, sodium tri-polyphosphate, sodium sulphate and a compound of the above general formula is spray dried to give a detergent powder.ALSO:The invention comprises di-[benzimidazyl-(2)]-ethylene compounds having the formula <FORM:0880484/IV (b)/1> in which m and n represent whole numbers of at most 2. The compounds are prepared (1) by reacting a compound having the formula <FORM:0880484/IV (b)/2> with a glycerol-a -chlorohydrin, or with ethylene chlorohydrin, when m and n are both equal to 2; (2) by saponi-fication of a compound of the formula <FORM:0880484/IV (b)/3> (3) by dehydrating a compound of the formula <FORM:0880484/IV (b)/4> (4) by dehydrohalogenating a compound of the formula <FORM:0880484/IV (b)/5> (5) by dehydrating a compound of the formula <FORM:0880484/IV (b)/6> (6) by reacting a compound of the formula <FORM:0880484/IV (b)/7> in the molecular ratio of 2:1 with thiomalic acid or aspartic acid or functional derivatives thereof; (7) by reacting a compound of the formula <FORM:0880484/IV (b)/8> with fumaric acid or with a fumaric acid dialkyl ester; and (8) by reacting a carboxylic acid of the formula <FORM:0880484/IV (b)/9> or a functional derivative thereof, with a diamine of the formula <FORM:0880484/IV (b)/100> The products may be converted into salts with sulphuric, hydrochloric, acetic and tartaric acids.ALSO:Di - [benzimidazolyl - (2)]-ethylene compounds having the formula <FORM:0880484/IV (c)/1> in which m and n represent whole numbers of at most 2, are used to brighten cotton, regenerated cellulose, cellulose di- or triacetate, polyamide, polyacrylonitrile and polyester fibres. The compounds are prepared (1) by reacting a compound of the formula <FORM:0880484/IV (c)/2> with glycerol-a -chlorohydrin, or with ethylene chlorohydrin when m and n are both equal to 2; (2) by saponification of a compound of the formula <FORM:0880484/IV (c)/3> (3) by dehydrating a compound of the formula <FORM:0880484/IV (c)/4> (4) by dehydrohalogenating a compound of the formula <FORM:0880484/IV (c)/5> (5) by dehydrating a compound of the formula <FORM:0880484/IV (c)/6> (6) by reacting a compound of the formula <FORM:0880484/IV (c)/7> in the moleculor ratio of 2 : 1 with thiomalic acid or aspartic acid or functional derivatives thereof; (7) by reacting a compound of the formula <FORM:0880484/IV (c)/8> with fumaric acid or with a fumaric acid dialkylester and (8) by reacting a carboxylic acid of the formula <FORM:0880484/IV (c)/9> or a functional derivative thereof, with a diamine of the formula <FORM:0880484/IV (c)/100>
