    Abstract: Polyfunctional alcohols with at least two alcoholic hydroxy groups are effective agents for dispelling fog and clouds. Preferred solid compounds are the so called sugar alcohols, saccharides and polyvinyl-alcohol, as liquid compounds or compounds with a low melting point alkane-diols, -triols or polyols or their reaction products with oxalkylating agents. The said compounds are sprayed into fog or clouds in finely dispersed form. They may be used, optionally together with other fog and clouds dispelling agents.

    Abstract: Oxyalkylated addition products from ethylene oxide-propylene oxide block polymers and bis-glycidyl ethers, obtained by the addition of ethylene oxide-propylene oxide block polymers of the formula wherein R denotes methyl or ethyl, n and m are numbers which are so chosen that the content of polyethylene oxide groups is 5 to 80% of the molecular weight of the block polymer, and p is a number larger than 10, to bis-glycidyl ethers of the formula +TR wherein the R1's can be identical or different and denote hydrogen, C1-C4-alkyl or halogen, in particular chlorine, A denotes a direct bond, a sulfonyl or cyclohexyl group or a group of the formula R2 denotes hydrogen, methyl or phenyl, and a denotes an integer from 0 to 10, and subsequent oxyalkylation with propylene oxide or butylene oxide and, if appropriate, ethylene oxide, the amount of propylene oxide or butylene oxide which is added last being 1 to 90% by weight of the total molecule and the amount of ethylene oxide which, optionally, has also been added, being 50% by weight of the total molecule. These addition compounds are used for breaking crude oil emulsions.
