Detergent composition and process of preparing same

Claim 1

IN THE PROCESS OF PREPARING AN IMPROVED ALKYLOLAMINE DETERGENT FROM PRODUCTS COMPRISING ESSENTIALLY THE CONDENSATION PRODUCT OF AN ALKYLOLAMINE HAVING AT LEAST 1 ACYLATABLE HYDROGEN ATOM IN THE AMINO GROUP AND A FATTY CARBOXYLIC ACID ACYLATING MATERIAL HAVING FROM 8 TO 14 CARBON ATOMS IN THE CARBOXYLIC ACID GROUP IN A RATIO OF AT LEAST 1.5 MOLES OF ALKYLOLAIME TO ONE MOLE OF CARBOXYLIC ACYLATING MATERIAL, SAID MATERIALS BEING HEATED AT A TEMPERATURE OF BETWEEN 120* C. AND 250* C. FOR A PERIOD OF BETWEEN 15 MINUTES AND 16 HOURS IN THE PRESENCE OF AN EXCESS OF BETWEEN 1/2 AND 10 MOLS OF THE ALKYLOLAMINE TO FORM ALKYLOLAMIDE AND ALKYLOLAMINE ESTER CONDENSATION PRODUCTS, AND THEN COOLING BELOW 100* C. AND MAINTAINING THE SAID PRODUCTS AT A TEMPERATURE OF BETWEEN 40* C. AND 90* C. FOR A PERIOD OF BETWEEN 4 AND 100 HOURS TO FORM REACTION PRODUCTS CONTAINING COMPOUNDS HAVING A SINGLE REPLACEABLE HYDROGEN ATOM OF THE ALKYLOLAMINE REPLACED WITH AN ACYL GROUP, THE IMPROVEMENT WHICH COMPRISES; REACTING A HIGHER CARBOXYLIC ACID ACYLATING MATERIAL HAVING MORE THAN 14 CARBON ATOMS IN THE CARBOXYLIC ACID GROUP WITH THE EXCESS ALKYLOLAMINE PRESENT IN THE CONDENSATION REACTION MIXTURE AFTER COOLING BELOW 100* C. TO FORM BETWEEN APPROXIMATELY 10 AND 50 PERCENT OF A HIGHER ALKYLOLAMINE SOAP IN SAID MIXTURE, THEREBY IMPROVING THE DETERGENT PROPERTIES AND SUPPRESSING THE SUDSING PROPERTIES OF THE SAID REACTION PRODUCTS.
