| titleOfInvention | Tertiary amine esters acid addition salts and quaternary ammonium compounds thereof and their preparation |
| abstract | 1355220 Tertiary amine esters BRISTOLMYERS CO 4 Nov 1971 [4 Nov 1970 (2)] 51360/71 Heading C2C [Also in Division C3] Compounds of formula where B is or NR<SP>5</SP>, R<SP>1</SP>, R<SP>2</SP> are C 1-18 alkyl, or aralkyl, R<SP>5</SP> is (CH 2 ) 4 or (CH 2 ) 5 , optionally substituted with C 1-8 alkyl, R<SP>3</SP> is H or C 1-18 alkyl, R is H, C 1-18 alkyl, aryl or aralkyl, R<SP>4</SP> is a carboxy acid acyl radical with 2-27 C atoms, n has an average value of 5-50, A is an anion of valency y, and m and p are both 1, or m is 0 and p is 0 or 1, may be prepared in the tertiary amine form by acylating the corresponding tertiary amine alcohol, preferably with R<SP>4</SP>Cl, and may then be quaternized or converted into acid addition salt form. If the amine alcohols have been obtained in admixture with polyglycol ethers they may be purified before or preferably after acylation by forming an aqueous acid solution of the mixture, extracting with a water-immiscible organic solvent, e.g. diethyl ether or ethyl acetate, and recovering the amine alcohol or ester from the aqueous phase. In examples n is 7, R<SP>3</SP> is CH 3 , R<SP>1</SP> and R<SP>2</SP> are C 2 H 5 , and R<SP>4</SP> is acetate, laurate, stearate or p-nitrobenzoate, and the products are obtained in tertiary amine form, in quaternized form with CH 3 Cl, and in salt form with HCl. The nitrobenzoate is reduced to form the corresponding p-aminobenzoate. |
