| titleOfInvention | New quaternary ammonium compounds |
| abstract | One or more esters of acrylic and/or methacrylic acid in monomeric, dimeric or oligomeric form are reacted with secondary bases and then quaternated, the esters used as starting materials having at least 8 carbon atoms and not having tertiary amino or quaternizable heterocyclic groupings in the alcohol residue. Both steps are preferably carried out under pressure, and under conditions such that the product is obtained as an emulsion, e.g. by adding the quaternizing agent to a stirred aqueous emulsion of the tertiary aminoester. The secondary base used may be aliphatic, aromatic, araliphatic or heterocyclic, the quaternizing agent being an alkyl or aralkyl halide or a dialkyl sulphate. The products are bactericides and emulsifying agents. In the examples: (1) hexanediol-1 : 6-dimethacrylate is reacted with dimethylamine and quaternated with methyl iodide; (2) C12- C18 alcohols methacrylate is reacted with dimethylamine and quaternated with dimethyl sulphate in an emulsion of spindle oil, or with benzyl chloride; (3) decyl methacrylate is treated with dimethylamine in the presence of catechol, and quaternated with methyl chloride; (4) decyl methacrylate is treated successively with morpholine and methyl iodide; (5) methyl methacrylate dimer is treated with dimethylamine and quaternated with dimethyl sulphate. In all the examples the intermediate tertiary amino-ester is isolated. Other specified reagents are diethylamine, piperidine and ethyl bromide.ALSO:Bactericidal, surface-active and emulsifying compositions contain quaternary ammonium compounds obtained by quaternating tertiary amino esters prepared by reacting secondary amines with esters of acrylic and/or methacrylic acid in monomeric, dimeric or oligomeric form; the esters used as starting materials have at least 8 carbon atoms and do not have tertiary amino (or quaternisable heterocyclic) groupings in the alcohol residue; the compositions preferably contain also about 10 per cent of the tertiary amine used in the preparation of the quaternary compounds. They may be used in emulsion form (e.g. with spindle oil in water) and in association with enzymes, particularly for cleaning surgical instruments, dairy apparatus or crockery, or the treatment of laundry linen. Specified compounds are derived from (a) hexanediol-1 : 6 dimethacrylate, mixed C12-C18 methacrylate, decyl methacrylate or the dimer of methyl methacrylate, (b) dimethylamine, diethylamine, morpholine or piperidine, and (c) dimethyl sulphate, benzyl chloride, methyl iodide or ethyl bromide. |
