Abstract
PURPOSE:To enable excellent pour point depressing and flowability improving actions at a temp. above the pour point to be exhibited on petroleum, by adding to crude oil, fuel oil or the like a lipophilic polyamine formed by replacing an active hydrogen atom directly bonded to a nitrogen atom in a particular polyamine with a higher aliph. hydrocarbon group. CONSTITUTION:An additive for petroleum comprising a lipophilic polyamine formed by replacing part or the whole of active hydrogen atoms directly bonded to a nitrogen atom in a polyamine (1) having an MW of 200-100,000 with at least one 8-40C straight-chain or branched aliph. hydrocarbon group. It is pref. that the wt. ratio of the constituent unit contg. an amino group to the constituent unit contg. an aliph. hydrocarbon group with respect to the lipophilic polyamine be 1:0.01-1:50. The lipophilic polyamine can be prepd. by reacting a polyamine (1) with at least one compd. having in its molecule a functional group reactive with an amino group and an 8-40C straight-chain or branched aliph. hydrocarbon group.
