Abstract (en)

[origin: EP0413279A1] Use of reaction products of alkenyl-spirobislactones of the formula <IMAGE> in which R is C8-C200-alkenyl in each case, with amines of the formula NR<1>R<2>R<3>, where R<1>, R<2> and R<3> can be identical or different and at least one of these groups R<1>, R<2> or R<3> is C8-C36-alkyl, C8-C36-alkenyl or cyclohexyl and the other groups are hydrogen or a group of the formula -(A-O)xH or -(CH2)n-NYZ, A-C2H4- and/or -C3H6-, x is a number from 1 to 20, n is 2 or 3 and Y and Z can be identical or different and are hydrogen or a group of the formula -(A-O)xH, as paraffin dispersants in middle distillates and crude oil.
