Abstract:
PROBLEM TO BE SOLVED: To obtain a polyamine of an acylated polymer in which a part of nitrogen atoms of the polyamine have long chain acyl groups and the other parts have short chain acyl groups, useful for an aqueous preparation, preferably a viscosity increasing agent for cosmetic composition or the like. SOLUTION: The polyamine of the acylated polymer in which a part of the nitrogen atoms of the polyamine have the acyl groups expressed by formula I (R1 is a 7-27C alkyl, a 7-27C alkenyl or a 7-27C hydroxyalkyl) and a part of the nitrogen atoms have groups expressed by formula II (R2 is a 1-6C alkyl or a 1-6C hydroxyalkyl). The polymer polyamine preferably have 0.3-40% of the nitrogen atoms of the polymer are acylated by the acyl groups expressed by formula I and 5-100% of the nitrogen atoms are preferably acylated. This polymer polyamine can be obtained by reacting a carboxylic acid expressed by formula R1-COOH or a carboxylic acid expressed by formula R2-COOH. This polymer polyamine is expected in use for a viscosity increasing agent.

Abstract:
Rapid dehydration of crude oils containing salt water by addition of minor amounts of polyalkylene polyamines having at least fifty recurring ethylene imine or propylene imine units, the said polyalkylene polyamine being completely alkoxylated at the nitrogen atom with from 10 to 300 moles of ethylene oxide and/or propylene oxide. Using these compounds it is possible to effect dehydration, in an economical manner, of crude oils containing up to relatively large percentages of high molecular weight hydrocarbons.
