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 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.
