摘要:
.beta.-Aminonitriles of the following formula I ##STR1## where R.sup.1 is an aliphatic hydrocarbon radical having alkyl side groups and a number average molecular weight of from 250 to 5,000 and R.sup.2, R.sup.3 and R.sup.4, independently of one another, are each hydrogen or C.sub.1 -C.sub.8 -alkyl and R.sup.2 or R.sup.4 is also phenyl, and alkylpropylenediamines prepared from the .beta.-aminonitriles by hydrogenation are used as additives in fuels and lubricants.

摘要:
Fuels for internal combustion engines or lubricants contain small amounts of polyisobutylaminoalcohols of the formulae Ia and Ib where R is polyisobutyl having a number average molecular weight of 500 to 5,000 and in each of the two formulae one of the radicals X is OH and the other is the group where the radicals R1 may be identical or different and are each hydrogen, alkyl, hydroxyalkyl or aminoalkyl which may be substituted by further hydroxyl- or amino-carrying alkyl radicals, or the two radicals R1 may form a nonaromatic ring.
摘要:
Halogen-free fuel additives based on a long-chain hydrocarbon having a polar terminal group are obtained by reacting a hydroformylated olefin with a polyamine and hydrogenating the reaction product.

摘要:
A glycol-based antifreeze mixture which is free of nitrites and phosphates contains an alkali metal salt of a C.sub.4 -C.sub.16 -alkenylsuccinic acid, stabilized silicate and further corrosion-inhibiting additives.
摘要:
Carbamates having a long-chain N-alkyl radical, a process for the preparation of the carbamates in a conventional manner and fuels and lubricants which contain these carbamates as additives.
摘要:
Fuels for gasoline engines contain a combination of a nitrogen-containing detergent component and an alkoxylate as a carrier oil component, the alkoxylate being a dialkylphenol-initiated propoxylate.
摘要:
A bag is disclosed for covering an endless track or chain of a tracked heavy equipment vehicle during transport. The bag includes an outer segment for covering an outer portion of the track extends laterally beyond side edges of the trailer flatbed. Forward and rearward lobes of the bag, respectively engage and cover forward and rearward ends of the track. An inner bag segment engages and covers the track between the side edges of the flatbed trailer supporting the tracked vehicle. A recess in an inside segment of the bag accommodates a track and allows the track to directly engage the supportive trailer. Tensioning straps and cords are used to further secure the bag to the track.
