Abstract

509,550. Pour-point depressant for oils; ketonic condensation products. STANDARD OIL DEVELOPMENT CO. Sept. 21, 1938, No. 27531. Convention date, Dec. 3, 1937. [Class 91] [Also in Group IV] A wax-modifying agent or pour-point depressant is prepared by condensing a halogensaturated aliphatic hydrocarbon or olefin with an aromatic hydrocarbon, and recondensing the product with an acyl halide. The condensations may be carried out in the presence of a catalyst. The acyl halide may be a derivative of a mono-or dibasic saturated aliphatic acid or of an aromatic or hydroaromatic acid. Thus, 100 parts by weight of chlorparaffin (12 per cent. of chlorine) is condensed with 15 parts by weight of naphthalene using 2¢ parts by weight of aluminium chloride as catalyst at 88‹F. and in 87¢ parts of kerosine as solvent. After 4¢ hours, the catalyst is hydrolyzed by adding isopropyl alcohol and aqueous caustic soda and removed. The product is distilled and condensed with acetyl chloride using tetrachlorethane as the solvent medium. By using different amounts of acetyl chloride and differing amounts of aluminium chloride, products with a differing effect on the pour points of oils are obtained. Other tests were carried out with the product obtained by condensing the first condensate with chloroacetyl chloride.
