C09D 516

US Classification:

428541

Abstract:

This invention relates to new and improved chlorinated phenol water soluble wood treating compositions and methods for preservation of wood or products made from wood. In the general practice of this invention, wooden objects are treated with water soluble wood treating and preserving solutions consisting of blends of from 0. 1% to about 50% by weight of a chlorophenol selected from a group consisting of pentachlorophenol and tetrachlorophenol and mixtures thereof, from about 1% to about 97% by weight aliphatic alcohols having from 1 to 6 carbon atoms and mixtures thereof, from about 0. 2% to about 35% of a fatty acid amine oxide or a mixture of fatty acid amine oxides and other amines, and from about 1% to about 97% by weight water. In addition, these wood treating formulations may contain up to 10% by weight of added ingredients selected from the group of tetrasodium pyrophosphate, copper salts, sodium chromates, sodium gluconate, sodium citrate, sodium N-dihydroxyethylglycinate and/or up to 20% by weight ammonium or sodium lignin sulfonate. In practice of this invention, these compositions are incorporated into treating systems that adequately penetrate wood and deposit essentially non-leachable chlorophenols in the wooden objects.

Abstract:

This invention relates generally to water soluble wood treating compositions and methods for preservation of wood or products made from wood. In the general practice of this invention, wooden objects are treated with water soluble wood treating and preserving solutions consisting of blends of (A) from 0. 1% to about 50% by weight of a chlorophenol selected from a group consisting of pentachlorophenol and tetrachlorophenol and mixtures thereof (B) from about 2% to about 98% by weight aliphatic alcohols selected from the group consisting of n-butyl alcohol, secondary butyl alcohol, isobutyl alcohol, tertiary butyl alcohol and isopropyl alcohol and mixtures thereof (C) from about 0. 56% to about 45% of an amine selected from the group consisting of ammonium hydroxide, triethyl amine, trimethyl amine, methyl amine and methyldiethanolamine and mixtures thereof and (D) from about 1% to about 97% by weight water. In addition, these wood treating formulations may contain up to 10% by weight of added ingredients selected from the group of tetrasodium pyrophosphate, copper salts, sodium chromates, sodium gluconate, sodium citrate, sodium n-dihydroxyethylglycinate and/or up to 20% by weight ammonium or sodium lignin sulfonate.

International Classification:

C07C 3906

US Classification:

260624C

Abstract:

Improvement in a method for producing para-alkylated phenols comprising reacting (A) a phenol and (B) an alkylating agent in the presence of (C) an alkylation catalyst and resulting product. This improvement comprises using as (C) an aryl sulfonic acid selected from the class of highly acidic aryl sulfonic acids having a K value of at least 3. 8. times. 10. sup. -. sup. 3 including para-chlorobenzene sulfonic acid, 4,4'-diphenyldisulfonic acid, nitrobenzenesulfonic acids, 2,4,6-trinitrobenzenesulfonic acid and meta-benzenedisulfonic acid and also trifluoromethanesulfonic acid. These acid catalysts are also very effective in rearranging ortho and meta substituted phenols to parasubstituted phenols allowing use of normally discarded by-products as starting materials.
