摘要:The synthesis of phenol sulfonate esters of alkanoyl amino acids is conducted in the presence of aqueous base to provide bleach activator compounds. Thus, the acid chloride of N-nonanoyl-6-aminocaproic acid is reacted with the sodium salt of p-phenol sulfonate in the presence of water at a pH in the range of about 9 to about 12 to yield the corresponding phenol sulfonate ester. The synthesis of the phenol sulfonate ester of the monononyl amide of adipic acid is also illustrated.

标题:Solventless synthesis of hydrophilic phenol ester derivatives
发明人：MAJERCZAK VICTORIA ANN; GIBSON MICHAEL STEVEN; ORLANDO ROBERT JAMES
摘要:Process for preparing benzenesulfonate salts from an appropriately substituted acid chloride and a hydroxybenzenesulfonic acid is conducted in the absence of solvent, in a molar excess of acid chloride and in the presence of a phase transfer catalyst selected from quaternary ammonium and quaternary phosphonium salts and the target reaction product. The molar excess of the acid chloride is used to reduce the occurrence of gelation in the product.

标题 :Synthesis of hydrophilic phenol ester derivatives
发明人：HARDY FREDERICK E; THOMPSON JAMES E
权利人:PROCTER & GAMBLE
摘要:A hydrophilic phenol ester derivative, especially a sulphonated or carboxylated phenol ester is prepared by reacting a C 6 -C 18 substituted or unsubstituted aliphatic carboxylic acid with a C 2 -C 3 alkanoic anhydride, and reacting the resultant C 6 -C 18 acid anhydride with a substituted phenol such as an alkali metal phenol sulphonate salt or hydroxybenzene carboxylic acid to give a C 6 -C 18 acyloxy derivative of a substituted benzene. The two stage process may be carried out in the same reaction vessel without the use of solvents. The products are useful as peroxyacid bleach precursors.

摘要:The invention relates to the synthesis of compounds with anti-retroviral activity. The synthesis of substantially pure aurintricarboxylic acid monomer and structurally defined polymers, analogs and derivatives thereof, is described. The compounds are shown to have potent anti-retroviral activity, particularly against HIV-1.
