    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.

    IPC: C09K3/18

    Abstract: Deicing/antiicing fluids for aircraft which contain essentially glycols, crosslinked polyacrylic acid, a nonionic surfactant based on alkoxylated C10-C20 alcohols, corrosion inhibitors, a mixture of NaOH and KOH, an antioxidant and water, reduce the loss of lift by having improved runoff characteristics from the wings while giving a refreeze holdover time of not less than 30 minutes.

    IPC: C09K3/18

    Abstract: An agent for thawing surfaces covered with ice and/or snow consists of or contains a mixture of at least one water-soluble monohydric alcohol, at least one water-soluble polyhydric alcohol, and formamide and/or a formamide derivative in which the proportion of monohydric alcohol or alcohols is from 40 to 90% by weight and the proportion of formamide or derivative thereof is from 10 to 60% by weight, both with reference to the total amount of alcohols. From 5 to 50% of a monoether of ethylene glycol or diethylene glycol may also be included. The monohydric alcohol may be methanol, ethanol, propanol or isopropanol: the polyhydric alcohol may be glycerin or ethylene, propylene, butylene, hexylene, diethylene, triethylene, dipropylen or tripropylene glycol. A suitable formamide derivative is an alkyl formamide such as monomethyl or dimethyl formamide. As corrosion inhibitors, a fatty acid polyamide and an acetylene derivative may be included.
