    Abstract: 1362013 Polyolefin derivatives STANDARD OIL CO 25 Aug 1971 [31 Aug 1970] 39897/71 Heading C3P [Also in Division C5] Oil-soluble aliphatic acid modified Mannich condensation products are prepared by reacting at 150‹ to 325‹ F. (a) a polyolefin substituted phenol derived from a polyolefin of molecular weight 600 to 100,000, (b) an amine containing at least one NH group and (c) an aliphatic aldehyde, or a reaction product of (a), (b) and (c), with (d) an aliphatic acid containing at least 6 carbon atoms, in molar ratios of 1 to 0À7-1À0 to 1À5-2À1 to 0À014-1À0 respectively, slowly adding to the resulting product 2 to 6 moles of additional aliphatic aldehyde per mole of (a), and dehydrating the resulting mass by raising the temperature thereof, e.g. by adjusting the temperature of the reaction mass to 275‹ to 375‹ F. and blowing with an inert stripping gas. In examples, polybutenyl phenols and tetraethylene pentamine are reacted with (I) formalin and C 16-18 fatty acids and (II) formaldehyde and oleic acid, and after addition of (I) formalin and (II) paraformaldehyde the products are blown with nitrogen.

    Abstract: OLEFIN SULFONATES Viscous liquid propene or butene polymers having number average molecular weights of about 250-500 are converted to the corresponding oilsoluble ammonium alkenyl sulfonates by treatment of the polymer with gaseous sulfur trioxide in a falling-film reactor, separation of the oilsoluble polymer sulfonic acids and oil-soluble polymer sultones from the sulfonation product mixture, and neutralization of the sulfonic acids and sultones with anhydrous ammonia.
