Crop oil concentrates are disclosed which increase the herbicidal efficacy of herbicides from diverse chemical classes. These crop oil concentrates comprise an anionic polyoxyalkylene surfactant or salt thereof, an adjuvant which is exclusively a fatty acid or its ester, and a hydrocarbon component. These crop oil concentrates are especially effective with cyclohexenone and triketone herbicides and growth regulators.

Polyethers having molecular weights of about 1000 to about 75,000 modified with alpha-olefin oxides having about 12 to about 18 carbon atoms exhibit increased thickening efficiency in aqueous systems. About 1 to about 20 percent by weight based upon the weight of the polyether is required, the proportion of alpha-olefin oxide modifier varying inversely with the molecular weight of the polyether. Modified polyethers, processes for the preparation of thickened aqueous systems, and thickened aqueous compositions are disclosed. The modified polyether thickening agents of the invention are particularly useful for thickening water or water-glycol mixtures which are useful as hydraulic fluids.

Polyethers modified with alpha olefin oxides

This invention relates to a process for preparing certain sulfophenethylsiloxanes by reacting nearly equimolar amounts of chlorosulfonic acid with certain phenethyltrichlorosilanes in the presence or absence of a solvent according to the specified reaction conditions.

Polyether-based thickeners for aqueous systems having molecular weights of about 1000 to about 75,000 which are modified with at least one glycidyl ether having about 12 to about 18 carbon atoms exhibit increased thickening efficiency in the presence of certain organic additives. These are ethoxylated phosphate esters or mixtures of said esters with water-soluble amines. The polyethers contain about 1 to about 20 percent by weight based upon the weight of the polyether of an alpha-olefin oxide. Polyether-based thickeners containing at least one of an ethoxylated phosphate ester, or said ester in admixture with a water-soluble amine, processes for the preparation of thickened aqueous systems, and thickened aqueous compositions are disclosed. The polyether-based thickeners of the invention are particularly useful for thickening water or water-glycol mixtures which are useful as hydraulic fluids.

The polyether-based thickeners of the invention are particularly useful for thickening water or water-glycol mixtures which are useful as hydraulic fluids.

Water-based hydraulic fluids and metalworking lubricants are disclosed which are thickened with a polyether polyol having a molecular weight of about 1000 to about 75,000 modified with an alpha-olefin epoxide having about 12 to about 18 carbon atoms. Unexpectedly, synergistic thickening results from a combination of said polyether polyol with the components of a water-based hydraulic fluid or metalworking lubricant. The particularly effective components of the hydraulic fluid or metalworking lubricant are the phosphate ester and water-soluble amine corrosion inhibitor components. The hydraulic fluid and metalworking fluids of the invention also contain a water-soluble polyoxyethylated ester of an aliphatic acid and a monohydric or polyhydric aliphatic alcohol, either one or both said acid and said alcohol being polyoxyethylated, a sulfurized molybdenum or antimony compound and a metal deactivator as well as other adjuvants conventional in this art.

Silicate fouling on the reboilers and trays and the distillation train used for the production of dihydric alcohols is arrested by the addition of caustic to the feed stream.
