Chemistry is traditionally divided into organic and inorganic chemistry. Recommanded Product: (cis-Tetrahydrofuran-2,5-diyl)dimethanol, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 2144-40-3

Biomass-derived 5-hydroxymethylfurfural (HMF) has been emerged as a key platform chemical for the production of fine chemicals and liquid fuels. The direct transformation of cellulose and lignocellulosic biomass into HMF in ionic liquids and organic solvents is most desired in terms of process economics and sustainability. The focus of this review is purely on the HMF production from cellulose and lignocelluloses and mechanistic aspects of HMF formation in order to bridge the gap in understanding the factors responsible for selective conversion and selection of catalyst. Additionally, present review is devoted exclusively to the latest developments, namely microwave-assisted degradation of cellulose to HMF, application of solid acid and ionic-liquid catalysis to address their effectiveness for HMF production. Approaches for the cellulose transformation into HMF are especially emphasized in order to explore newer avenues of biomass as renewable feedstock for energy and chemicals.

Reference of 13031-04-4, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 13031-04-4, 4,4-Dimethyldihydrofuran-2,3-dione, introducing its new discovery.

3,4-Bis{[2-(methyl-phenyl-oxophosphanyl)-ethyl]phenyl-phosphanyl} pyrrolidines have been synthesized by Michael Addition from the corresponding methyl-phenyl-vinyl-phosphane oxides and 3,4-bis(phenylphosphino)pyrrolidines. For purification of the ligands palladium complexes were used and with the enantiomerically pure ligands Rh complexes have been prepared. The catalyst has 6 stereogenic centers. In the hydrogenation of Z-alpha-acetamidocinnamic acid all six stereogenic centers have an influence on the enantioselectivity. The influence is strongest from the C stereocenters of the pyrrolidine ring. Less important are the stereogenic centers on the coordinated P atoms. The influence of the stereocenters on the non-coordinated P=O groups is the least, but it is not negligible. The ee values obtained with the ligands containing P=O groups are much lower than those obtained with ligands which are substituted only with aryl groups. Ketones are hydrogenated with only low ee’s.

A simple and efficient one-pot approach for assembling novel spiro[indolepyranopyrrole] derivatives was developed and used to prepare a series of biologically important compounds. The reaction was easily performed with high efficiency under very simple and mild conditions without any catalysts and it gave good yields, avoiding time-consuming costly synthesis and laborious workup and purification of products. The cytotoxic activities of these new spiro[indolepyranopyrrole] derivatives were evaluated in vitro. Most of the tested compounds exhibited significant cytotoxicities to Raji cell lines.

Abstract Poplar (Populus nigra) flash pyrolysis has been performed at the IK4-Ikerlan 25 kg h-1 pilot plant equipped with a conical spouted bed reactor. Gas, bio-oil and char yields and properties have been studied in the 425-525C range. This reactor has been proven to be especially suitable for this process as high bio-oil yields have been obtained, with the maximum being 69 wt.% at 455C. The bio-oil has been collected in two fractions: the lighter one, which accounts for 85 wt.% of the bio-oil, has a high water content and is composed mainly of acids and ketones, whereas the heavier fraction has a lower water content and is rich in phenols. These fractions are miscible, obtaining a bio-oil with a water content lower than 25 wt.% and a higher heating value in the 16-18 MJ kg-1 range.
