  • Patent number: 9676924
    Abstract: A method of making a benzyl cis-cyclohexane 1,2-dicarboxylate triester having the steps: a. forming a reaction mixture by reacting the following three components: i. a synthetic or biobased reagent selected from the group consisting of an alpha-hydroxyester and a beta-hydroxyester, ii. an anhydride selected from the group consisting of cis-hexahydrophthalic anhydride, 4-methylcyclohexane-1,2-dicarboxylic anhydride, and 3-methylcyclohexane-1,2-dicarboxylic anhydride, and iii. an alkylamine catalyst; and b. contacting benzyl chloride with the reaction mixture to yield a product that is free of phthalates and includes at least one benzyl cis-cyclohexane 1,2-dicarboxylate triester.

  • Patent number: 5872248
    Abstract: A simple, flexible, convenient method for making silicon phthalocyanines and naphthalocyanines by inserting silicon into metal-free phthalocyanines and metal-free naphthalocyanines is provided. The method comprises: providing a metal-free phthalocyanine or metal-free naphthalocyanine; reacting the metal-free phthalocyanine or metal-free naphthalocyanine with HSiCl.sub.3 to provide a reaction product; then reacting the reaction product with water; and extracting a silicon phthalocyanine or a silicon naphthalocyanine. The invention also relates to novel phthalocyanines and naphthalocyanines. The phthalocyanines and naphthalocyanines are useful as photosensitizers and as dyes.
