标题:Process for the synthesis of 2-hydroxyphenyl alkyl ketones
发明人：BORZATTA VALERIO; POLUZZI ELISA; VACCARI ANGELO
权利人:ENDURA SPA
摘要:A process is described for the synthesis of 2-hydroxyphenylalkyl ketones, by means of catalytic rearrangement of phenolic esters. This process is characterized by the use, as catalysts, of crystalline aluminosilicates of the pentasyl type having predefined values of silica/alumina ratio, grain size, surface area and porosity, and containing between 10 wt% and 40 wt% of finely ground alumina as bonding agent. The rearrangement thus catalyzed involves a high conversion of the phenolic ester, a high orthoselectivity and a low formation of phenolic by-products, thus enabling the formation of the end product in high yields. In particular, the process applies to the synthesis of 2-hydroxyacetophenone.

权利人:DNA SCRIPT
摘要:Methods are provided for template-free enzymatic synthesis of polynucleotides on a solid support using double cleavage to produce scarless polynucleotides. In particular, methods are disclosed that use an initiator that comprises a cleavable group, which can be cleaved by a small molecule chemical agent, adjusting pH, heat, or photocleaved by illumination with light to release polynucleotides from a solid support after enzymatic synthesis is completed, and an enzymatic cleavage site, which can be cleaved by a cleavage enzyme to remove polynucleotide scars.

标题 :Synthesis and polymerization of vinyl triazolium ionic liquids
发明人：LUEBKE DAVID; NULWALA HUNAID; MATYJASZEWSKI KRZYSZTOF; ADZIMA BRIAN
权利人:US ENERGY; THE US DEPARTMENT OF ENERGY
摘要:Herein, we describe polymerized ionic liquids, demonstrate the synthesis of polymerized ionic liquids, and demonstrate the polymerization of triazolium monomers. One embodiment shows the polymeriazation of the triazolium monomers with bis(trifluoromethanesulfonyl)imide anions. In another embodiment we show the feasibility of copolymerizing with commodity monomers such as styrene using free radical polymerization techniques.

标 题 :Process for synthesis of 5-alkylbenzodioxoles
发明人：BORZATTA VALERIO; BRANCALEONI DARIO; BATTISTINI CHRISTIAN
权利人:ENDURA SPA
摘要:The following description refers to a new process for the synthesis of 5-alkylated benzo[1,3]dioxole, comprising the following steps in sequence: catalytic hydrogenation of 4-acylphenol; acylation; displacement catalysed by Lewis acids; treatment with an inorganic basic compound and hydrogen peroxide; reaction with alkyl dihalides or dialkoxyalkanes. n The process described herein, which yields 5-alkylbenzo[1,3]dioxoles, is economic and can be easily scaled up to industrial size.

摘要:In particular, the invention relates to the synthesis of radiation-curable polyurethane/oligomeric urethane dispersions of anionic and cationic characters, containing neutralization techniques characterized by the selection of counter ions as monomers and/or agents which can be polymers acting as promoters under radiation, to a radiation polyurethane/oligomeric urethane synthesis method that enables the creation of radiation curable binder systems without using cosolvents, surfactants, emulsifiers, defoamers, stabilizers and additives, wherein all components of the radiation-curable binder systems can be polymerized.
