摘要:A series of renewable bisphenols has been synthesized from creosol (2-methoxy-4-methylphenol) through stoichiometric condensation with short chain aldehydes. Creosol can be readily produced from lignin, potentially allowing for the large scale synthesis of bisphenol A replacements from abundant waste biomass. The renewable bisphenols were isolated in good yield and purity without resorting to solvent intense purification methods. Zinc acetate was shown to be selective catalyst for ortho-coupling of formaldehyde but was unreactive with more sterically demanding aldehydes. Dilute HCl and HBr solutions were shown to be effective catalysts for the selective coupling of aldehydes in the position meta to the phenol. Acid solutions could be recycled and used multiple times without decreases in activity or yield.

摘要:A process for the bulk polymerization, in the absence of any solvent, of a reactant containing azide functionality and a reactant containing a terminal alkyne functionality, in the presence of Cu (I) catalyst or in the presence of a Cu(II) catalyst without a reducing agent, is described. Polymerization can be achieved at temperatures less than 100° C., which is suitable for low temperature cures. A controlled synthesis for low molecular weight oligomers is disclosed.

摘要:The present invention relates to polysiloxane nanoparticles having the following properties: an average particle size d 50 (measured using REM recordings) in the range of 10-200 nm, a specific surface area A o of at least 50 m 2 /g, a pore volume of at least 0.2 cm 3 /g, an average pore volume d 50 of at least 0.8 nm, wherein the particles have groups that contain carbon, which groups are bonded to the silicon at least partially in the form of unsubstituted or substituted alkyl, alkenyl, aryl, arylalkyl, or alkylaryl groups. Said polysiloxane nanoparticles can be produced, among other things, in that either a silazane or a mixture of different silazanes having one or more —[Si(R)(R 1 )—NR 2 ]— units and/or a silane or a mixture of different silanes having the formula R′ x —SiX 4-a or an oligosiloxane obtainable by means of hydrolytic condensation of said silane/said silanes or a mixture of such oligosiloxanes are provided in a solvent and brought in contact with a strongly alkaline medium in such a way that the pH is not below 13 after the addition thereof. In specific embodiments, synthesis in acid is also successful.
