    Abstract: This invention provides a process for purifying the crude aromatic dicarboxylic acids produced by oxidation of dialkyl aromatic hydrocarbons and for using the purified acids in the preparation of polyethylene terephthalate, polyethylene naphthalate and other polyesters. The invention simplifies the manufacturing process by converting the crude aromatic acids into bis-glycol esters in an esterification reactor 4, from which the esterified partial oxidation impurities present in the oxidation product are removed by distillation in distillation tower 5. After removal of the volatile impurities, the dicarboxylic acid esters can separated by distillation in distillation tower 6 or by crystallization and converted to polyesters by polycondensation. The volatile impurities removed as overhead from tower 5 can be recycled as stream 16 to the oxidation reactor where they act as oxidation promoters thereby optionally allowing for a bromine-free oxidation process for dialkyl aromatic hydrocarbons.

The complexes are made by neutralizing a fatty ammonium compound that is cationic with an anionic compound, producing a salt complex. Optionally, the complex can be combined with dimethicone copolyol to produce extremely mild products suitable for use in shampoos, body washes, and cleanser. The mildness makes these compounds of particular interest in baby shampoos.

  • Patent number: 6184411
    Abstract: The invention is directed to an improved process for the preparation of a compound of formula (I) wherein R is alkyl, n is 0 to 2, m is 1 to 4 and A is alkyl, interrupted or uninterrupted alkylene, alkanetriyl or pentaerythrityl, by transesterifying the corresponding lower alkyl with a higher alkanol of the formula A-(OH)m in the presence of a tin catalyst; wherein the improvement comprises reacting the tin catalyzed transesterification reaction mass with a carboxylic acid or hydrate thereof neat, in the absence of an aqueous medium, until the tin catalyst forms an insoluble derivative, and then separating the insoluble derivative from the reaction mass by filtration without the assistance of a filtration aid. The invention allows for a convenient method by which to remove the residual tin catalyst from the substituted hydroxyphenylcarboxylic acid ester compounds of formula (I).
