Water-soluble copper salts

An improved process for preserving wood by impregnating the wood with metal salts is described. More particularly, the improved process comprises the steps of

Process for preserving wood

Water dispersible compositions containing hydrocarbon wax are described which are useful in preparing aqueous water repellent systems. Aqueous water repellent systems containing a hydrocarbon wax also are described. The water repellent system comprises an aqueous system comprising water, a saturated hydrocarbon wax, at least one oil-soluble metal salt of an organic carboxylic acid, at least one surfactant and at least one hydrocarbon solvent. A process for impregnating permeable substrates such as wood, cloth, concrete, rope, etc. with the water repellent system is also described. Penetration of the various components into the substrate is obtained by brushing, dipping, soaking, spraying or immersion at atmospheric pressure, at elevated pressures or under vacuum. The oil-soluble metal salt often is a fungicide. Moreover, additional components can be contained in the aqueous system such as insecticides, colorants, flame retardants, moldicides, wood stabilizing agents, etc.

Water dispersible compositions for preparing aqueous water repellent

In the extractive distillation of C.sub.5 hydrocarbons with different degrees of unsaturated using acetonitrile, an increase in the selectivity of acetonitrile is obtained when also using with acetonitrile small amounts of at least one compound selected from the group consisting of dimethylformamide, dimethylsulfoxide, morpholine, furfural, N-methylpyrrolidone, 3-methoxypropionitrile, gamma-butyrolactone, ethylene glycol monomethyl ether, diethylene glycol monomethyl ether, ethylene glycol monoethyl ether, and diethylene glycol monoethyl ether.
