Abstract: 1,2-Butylene oxide adducts (I) of alcohols (II) is produced by reacting (II) with 1,2-butylene oxide (III) in the presence of an alkali, using a (III):(II) molar ratio of more than 20:1. The reaction is effected at 120-160 (esp. 140-150) deg.C and 5-30 bar in the presence of 0.01-1 (esp. 0.05-0.5)wt.% KOH. The (III):(II) molar ratio is 20-500:1.

Abstract: A fuel for Otto engines contains a small amt. of cpds. of formula (I). In (I) R = polyisobutylene gp. with mol. wt. 500-5,000; R1 = H, Me or Et; m = 0 or 1. Pref. the fuel contains 50-5000 ppm of (I), and opt. other fuel detergents, antifreeze agents, corrosion inhibitors and/or antioxidants. In (I), the mol. wt. of R is 800-1500. (I) are prepd. by hydroformylation of a polyisobutylene R', followed by hydrogenative amination and reaction with ethylene oxide, propylene oxide or butylene oxide in presence of water. (R' = olefin with 1 fewer H than the gp. R). ADVANTAGE - (I) disperse oil sludge, in addn. to acting as carburettor detergents and valve cleaners.

Abstract: A sample quantity of fuel/oil/additive mixture is continuously metered (1) to a channel-shaped inclined test body (3), along which there is a rising temperature gradient. Under the increasing action of heat on the flowing mixture, solid residue products form on the test body after a certain distance of flow. Their weight and the distance of flow are assessed for the purpose of evaluating the additive.

Abstract: Fuels for spark-ignition engines contain small quantities of mono- or di-alkoxylated polyisobutylamines as additives for keeping the carburettor clean, cleaning the valves and dispersing oil sludge.
