    摘要: This invention describes processes to make products by cross metathesis of functionalized or non-functionalized olefins with poly-branched poly-olefins such as terpenes (e.g., farnesene(s), α-farnesene, β-farnesene, β-myrcene, etc.) and compositions made by such methods. More particularly, the present invention relates to methods of making (i) cross metathesis products by a cross metathesis reaction between at least one hydrovinylated olefinic substrate and at least one hydrovinylated cross metathesis substrate in the presence of at least one olefin metathesis catalyst; (ii) cross metathesis products by a cross metathesis reaction between at least one hydrovinylated olefinic substrate and at least one cross metathesis substrate in the presence of at least one olefin metathesis catalyst; and (iii) cross metathesis products by a cross metathesis reaction between at least one olefinic substrate and at least one hydrovinylated cross metathesis substrate in the presence of at least one olefin metathesis catalyst; as well as compositions made by such methods.

    摘要: A method for hydroxylating phenols and phenol ethers using hydrogen peroxide and specifically, a method for hydroxylating phenol using hydrogen peroxide. The method for hydroxylating a phenolic substrate selected from a phenol or a phenol ether by reacting such phenolic substrate with hydrogen peroxide in the presence of an acid catalyst comprises the following steps, implemented consecutively or simultaneously: a first step consisting of mixing a phenolic substrate with a hydrogen peroxide solution under conditions in which the temperature is sufficient for the initial phenolic substrate to remain liquid and for minimizing the conversion rate of the hydrogen peroxide; a second step consisting of carrying out the phenolic substrate hydroxylation reaction under adiabatic conditions, the acid catalyst being added at the mixing stage and/or at the beginning of the hydroxylation reaction; and a third step, if necessary, consisting of recovering the hydroxylated product.

    摘要: The present invention relates to an improved, fully-integrated continuous process of enhanced process operability for manufacturing copolyether glycols having enhanced physical properties by polymerization of a reaction mixture comprising tetrahydrofuran and at least one alkylene oxide in the presence of an acid catalyst and at least one compound containing reactive hydrogen atoms. The copolyether glycols manufactured by the present process have enhanced physical properties of increased alkylene oxide incorporation, average molecular weight and polydispersity, as well as reduced crystallinity, color, oligomeric cyclic ether content, and linear oligomer having an average molecular weight of up to about 400 dalton content.
