FREMGANGSMAADE TIL FREMSTILLING AF OXIDEREDE POLYISOBUTENER, DERES ANVENDELSE TIL FREMSTILLING AF ADDITIVER OG ANVENDELSE AF ADDITIVERNE |
摘要 |
Oxidised polyisobutenes, that is polyisobutenes containing ketonic and carboxylic acid carbonyl groups, are produced by passing through a column of the polyisobutene maintained at a temperature in the range from 140 to 200 DEG C and at atmospheric or elevated total pressure a molecular oxygen-containing gaseous oxidant at a gas flow rate greater than 10 litres cm<-><2>h<-><1> measured at the operating pressure. The oxidised polyisobutenes can be reacted for example with an aliphatic polyamine to produce a lubricating oil additive or with an aliphatic polyamine and formaldehyde to produce a fuels additive. |
