Abstract:
This invention relates to a process for recycling waste material selected from amino-carboxylic acid oligomers or polymers and amido-carboxylic acid oligomers or polymers into amido-carboxylic acids. A mixture containing water, an oligomeric or polymeric waste material, and a carboxylic acid is heated. The mixture is cooled to obtain a two phase system containing an aqueous phase and an organic phase which are separated. Carboxylic acids, unreacted starting materials, and the monomeric amido-carboxylic acid product are distilled from the organic phase. The remaining solid residue composed of high boiling oligomeric amino-carboxylic acids is recycled into Step (A).
Abstract:
This invention relates to a process for preparing amido-carboxylic acids in water. The process involves four steps. Step (A) involves hydrolyzing a lactam at a temperature of 150 DEG C - 300 DEG C to form a mixture containing an amino acid. Step (B) involves cooling the reaction mixture formed in step (A) to a temperature of 25 DEG C - 100 DEG C. Step (C) involves reacting a carboxylic acid anhydride with the amino acid formed in step (A) to form a reaction mixture containing an organic layer which contains an amido-carboxylic acid and an aqueous layer. Step (D) involves separating the amido-carboxylic acid containing organic layer from the aqueous layer. The presence of water aids in product isolation by phase separation and recycle of the reactants. Amido-carboxylic acids are used to make bleach activators for detergents.
Abstract:
Disclosed is a process for the recovery of a phytolipid composition from a vegetable oil by-product. The phytolipid composition produced comprises squalene, phytosterols, mixed tocopherols and tocotrieneols, and vegetable wax and is useful as an emollient. The phytochemical composition may be applied directly to the skin to provide emolliency. Alternatively, the phytoiipid composition may be formulated in various aqueous or anhydrous cosmetic compositions such as creams, lotions, gels, ointments, lip balms, sticks, or pencils for treatment of the skin and lips. The phytolipid composition also may be incorporated into foods, beverages, and nutraceuticals to provide health benefits.
Abstract:
The present invention relates to a one-step process for preparing amido-carboxylic acid esters having the amide nitrogen positioned between two carbonyl carbons by reacting a carboxylic acid or carboxylic acid ester with a monohydric alcohol and either a lactam, amino-carboxylic acid or a polymeric amino-carboxylic acid. In this process, amidation, esterification, alcoholysis, and hydrolysis reactions occur simultaneously.
Abstract:
This invention relates to a process for preparing amido ester compounds. The proces involves (I) forming a mixture in a reactor of a phenol derivative and an amido-carboxylic acid at a temperature which ensures at least partial solubility of the phenol derivative and the amido-carboxylic acid, and (II) adding a carboxylic anhydride incrementally to the mixture formed in Step (I) while distilling a by-product carboxylic acid from the reactor. The amido esters are useful as bleach activators.
Abstract:
This invention relates to a five step process for preparing a purified alkali metal salt of 4-sulfophenyl-[(1-oxyalkanoyl)amino]alkanoate in one reaction vessel without isolation of intermediates. The first step involves reacting an alkali metal salt of 4-hydroxybenzenesulfonic acid with a C2 to C4 carboxylic anhydride in a solvent to form an alkali metal salt of 4-acyloxybenzenesulfonic acid and a C2 to C4 carboxylic acid. The second step involves adding an [(1-oxyalkanoyl)amino]alkanoic acid and a transesterification catalyst to the reaction product of Step (A) and heating at a temperature and pressure sufficient to maintain reflux of the solvent and to remove the C2 to C4 carboxylic acid from the reaction vessel to form a reaction mixture containing an alkali metal salt of 4-sulfophenyl-[(1-oxyalkanoyl)amino]alkanoate. The third step involves removing solvent from the reaction mixture formed in Step (B). The fourth step involves mixing the alkali metal salt of 4-sulfophenyl-[(1-oxyalkanoyl)amino]alkanoate product of Step (C) with acetic acid. The fifth step involves separating the product from the acetic acid. The purified alkali metal salt of 4-sulfophenyl-[(1-oxyalkanoyl)amino]alkanoate product is useful as a bleach activator in detergents.
Abstract:
This invention relates to a four step process for purifying amido-carboxylic acids by liquid/liquid extraction from a reaction mixture containing an amido-carboxylic acid. The first step involves distilling impurities from a reaction mixture containing an amido-carboxylic acid to form a distillate residue. The second step involves mixing the distillate residue with a nonpolar hydrocarbon solvent wherein the mixture is maintained above the freezing point of the distillate residue. The third step involves allowing the hydrocarbon solvent and distillate residue to achieve phase separation of an organic phase containing the amido-carboxylic acid and an organic phase containing the nonpolar hydrocarbon solvent. The fourth step involves separating the organic phase containing the nonpolar hydrocarbon solvent from the organic phase containing the amido-carboxylic acid.
