Acyclic Polyoxy Alcohol Moiety Patents (Class 560/263)
  • Patent number: 9090578
    Abstract: The present disclosure provides a preparation method of glycidylester of tertiary carbonic acid. The synthesis is performed in two steps: first, the tertiary carbonic acid reacts with a halo substituted epoxide under a catalyst to produce tertiary carbonic halo substituted alcohol ester; after dehydrohalogenation of the halo substituted alcohol ester of tertiary carbonic acid, the glycidylester of tertiary carbonic acid is formed. In the first step of preparing the halo substituted alcohol ester of tertiary carbonic acid through synthesis, the reaction between the tertiary carbonic acid and the halo substituted epoxide is only performed in the existence of water and the catalyst, and the water comprises water added before the reaction. The present disclosure significantly increases the product output in the unit volume, and is particularly suitable for industrial production of glycidylester of tertiary carbonic acid having the low cost, high purity, low color and stable color.

    Abstract: A method for producing an ester comprising the steps of reacting an alcohol with a carboxylic acid to obtain a crude esterfied product, adding 5 to 100 parts by weight of a hydrocarbon solvent with respect to 100 parts by weight of the crude esterified product and performing neutralization with an alkali aqueous solution. An alcohol solvent can be added, if necessary. Thus, a method for producing an ester is provided in which a high-quality ester is obtained at a high yield.

  • Patent number: 6900347
    Abstract: Reaction mixtures and methods using catalysts and reaction conditions to produce significantly improved yields (and thereby higher purity) of olefin metathesis products, with greatly reduced amounts of impurities. These techniques include in one instance reduction in temperature of reaction, and in another, the use of chemical compounds that act as reaction inhibitors of unwanted reactions to minimize or prevent formation of unwanted impurities.

  • Patent number: 6586609
    Abstract: Process for the esterification of organic acids with alcohols in a reactor of the chromatographic type in which the heterogeneous solid phase is capable of acting both as an esterification catalyst and as a means exhibiting preferential adsorption towards one of the reaction products (typically water). The process to which the present invention relates is particularly improved compared with conventional technology owing to the use, as the means for regenerating the catalyst, of a desorbent to which has been added a second compound, generally the anhydride of the acid used in the esterification reaction, which, by chemical reaction, completes the removal of the adsorbed water.
