Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. 99395-88-7, Name is (S)-4-Phenyloxazolidin-2-one, molecular formula is C9H9NO2, belongs to oxazolidines compound. In a document, author is Ionescu, Mihail, introduce the new discover, Quality Control of (S)-4-Phenyloxazolidin-2-one.
Polyols and Rigid Polyurethane Foams from Cashew Nut Shell Liquid
Cashew nut shell liquid (CNSL) is a natural aromatic oil consisting of a mixture of phenolic structures with a carboxyl group in ortho position and substituted in meta position with a hydrocarbon chain of 15 carbon atoms. The major component of CNSL is anacardic acid (90 %), which is easily decarboxylated to cardanol by distillation. The present work describes the synthesis of new biobased Mannich polyols for rigid polyurethane foams in two steps: synthesis of Mannich bases by reacting phenolic ring of cardanol with N-(2-hydroxyethyl)-1,3-oxazolidine followed by alkoxylation reactions. The polyols were characterized by wet methods (hydroxyl numbers, viscosity, acid value, density, water content, iodine value etc.), spectroscopic methods (FT-IR, H-1 NMR and C-13 NMR) and by Gel Permeation Chromatography. The Mannich polyols from cardanol are excellent replacements for petrochemical derived Mannich polyols based on nonyl phenol. Cardanol-based polyols were used successfully for the preparation of rigid polyurethane foams of good physical-mechanical and fireproofing properties.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law. In my other articles, you can also check out more blogs about 99395-88-7. Quality Control of (S)-4-Phenyloxazolidin-2-one.
