摘要:
A middle distillate having a maximum um sulfur content of 0.05% by weight and containing fatty acid esters of alkoxylated polyols having at least 3 OH groups (A) and also at least one cold flow improver (B). The cold flow improver includes at least one copolymer of ethylene and one or more ethylenically unsaturated carboxylic esters having an ethylene portion of from 60 to 90 mol %.
摘要:
An additive for low-sulfur mineral oil distillates having improved cold flowability and paraffin dispersancy, comprising at least one ester of an alkoxylated polyol and at least one polar nitrogen-containing paraffin dispersant.
摘要:
Quadridentate Cu.sup.II and Zn.sup.II phenoxyl complexes and phenoxyl radical complexes thereof, in which one ligand L is bonded to each metal atom and H.sub.2 L stands for the general formula ##STR1## in which the bridge-unit Q stands for --S--, --O--, --N(R.sup.3)--, --P(R.sup.4)--, or ortho-NH--C.sub.6 H.sub.4 --NH-- and R.sup.1 and R.sup.2 stand for radical-stabilizing residues.Preferred radical complexes include ##STR2## The radical complexes are oxidation catalysts for oxidizing organic substrates with O.sub.2 in the course of which H.sub.2 O.sub.2 is also formed.
