NOVEL COMPOUNDS HAVING TWO TERMINAL HYDROXYMETHYL5-ALKYLBENZYL SUBSTITUENTS AND HAVING ALL ALKYL-SUBSTITENTS OF MOLECULAR WEIGHT UPWARD FROM ABOUT 400 ARE OBTAINED BY A STRONG ALKALI PROMOTED CONDENSATION OF 4-ALKYLPHENOL WITH FORMALDEHYDE. BECAUSE OF THE PRESENCE OF TWO HYDROXYMETHYL (METHYLOL) SUBSTITUTED ALKYLHYDROXYBENZYL GROUPS, THESE COMPOUNDS CAN BE CONSIDERED AS BIS-METHYLOLS SINCE THEY ARE MORE REACTIVE AS DIOLS THAN POLYPHENOLS. THESE COMPOUNDS THROUGH THEIR METHYLOL SUBSTITUENTS REACT WITH A COMPOUND HAVING AT LEAST ONE HN< GROUP TO FORM NOVEL OIL SOLUBLE AMINE PRODUCTS WHICH IMPART DETERGENCY-DISPERSANCY AND ANTIOXIDANT PROPERTIES TO THE OIL IN WHICH THEY ARE DISSOLVED. THEY ALSO REACT WITH MONO-ACIDS TO FORM SIMPLE DIESTRS, WITH DIBASIC ACIDS TO FORM HIGH MOLECULAR WEIGHT POLYESTERS, WITH AMMONIA TO FORM HIGH MOLECULAR WEIGHT AMINES HAVING SECONDARY AMINO GROUPS BRIDGING IN A CHAIN AND EVEN TERMINAL AMINO METHYL GROUPS AND WITH ALKYLENE DI- AND POLYAMINES TO FORM MORE COMPLEX OIL SOLUBLE AMINES WHICH AS SOLUTES IMPART TO SOLVENT OIL ANTI-OXIDANT, DETERGENT--DISPERSANT PROPERTIES. |
