Electric Literature of 15833-61-1, 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 Patent, and a compound is mentioned, 15833-61-1, (Tetrahydrofuran-3-yl)methanol, introducing its new discovery.

The invention discloses a method for synthesizing S-(+)-tetrahydrofuran-3-methanol. The method comprises the following steps: reacting D (+)-10-camphorsulfonic acid with thionyl chloride, so as to obtain D-(+)-10-camphor sulfonyl chloride; reacting D-(+)-10-camphor sulfonyl chloride with (+/-)-tetrahydrofuran-3-methanol, so as to obtain tetrahydrofuran-3-methyl camphor sulphonate; standing tetrahydrofuran-3-methyl camphor sulphonate to crystallize, performing configuration inversion in the crystallization process, so as to obtain tetrahydrofuran-3-methyl camphor sulphonate of single configuration, dissociating the crystal by using a dissociation agent, so as to obtain S-(+)-tetrahydrofuran-3-methanol. By adopting the method, the phenomenon that only 50% of single configuration can be obtained in the chiral resolution process is avoided, the yield is greatly increased, the synthesis route is short, and the operation is simple. The method is mainly applied to synthesis of a midbody, namely, S-(+)-tetrahydrofuran-3-methanol.

Application of 7331-52-4, Because a catalyst decreases the height of the energy barrier, its presence increases the reaction rates of both the forward and the reverse reactions by the same amount.7331-52-4, Name is (S)-4-Hydroxydihydrofuran-2(3H)-one, molecular formula is C4H6O3. In a article，once mentioned of 7331-52-4

Intact Crocus sativus petals were studied for the first time by high-resolution magic angle spinning nuclear magnetic resonance (HR-MAS NMR) spectroscopy, revealing the presence of kinsenoside (2) and goodyeroside A (3), together with 3-hydroxy-I-butyrolactone (4). These findings were confirmed by HR-NMR analysis of the ethanol extract of fresh petals and showed that, even though carried out rapidly, partial hydrolysis of glucopyranosyloxybutanolides occurs during extraction. On the other hand, kaempferol 3-O-sophoroside (1), which is NMR-silent in intact petals, is present in extracts. These results suggest to evaluate the utilization of saffron petals for phytopharmaceutical and nutraceutical purposes to exploit a waste product of massive production of commercial saffron and point to the application of HR-MAS NMR for monitoring bioactive compounds directly on intact petals, avoiding the extraction procedure and the consequent hydrolysis reaction.

Tangential flow filtration was tested for clarifying lemon juice for the food industry. Membranes with three different pore sizes were assayed: 100,000. Da (polysulfone), 0.20 mum (polypropylene), and 0.45 mum (polyvinylidene difluoride). Volatiles were extracted using a distillation technique and quantified by gas chromatography-mass spectrometry. The concentration of aroma compounds finally found in the clarified lemon juice (CLJ) increased with the membrane pore size and more apolar compounds were found in the CLJ obtained by using more hydrophobic membranes. The low concentration of terpene hydrocarbons of the lemon juices clarified using membranes of 100,000. Da and 0.45 mum made them ideal as acidulant agents in fruit preservation. On the other hand, the CLJ obtained using a membrane of 0.2 mum of pore size, with high recuperation percentages for terpene hydrocarbons (e.g. limonene) and aldehydes (neral and geranial), made this juice ideal for applications in which a lemon flavor is needed. One of the main results of this work lies in the fact that certain compounds reduce their concentration in a large percentage during the cross-flow filtration. This reduction is associated with its presence in the juice cloud and pulp whose are concentrated in the retentate. The elimination of these compounds is transcendental to use lemon juice as an acidifier because they are responsible for aromatic degradation in processed food, as, for example, canned peach halves in syrup. Therefore, the use of cross-flow filtration in the clarification allows the use of lemon juice as acidulant in food with very sensitive flavors to degradation during processing and storage.

The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 4971-56-6, Furan-2,4(3H,5H)-dione, introducing its new discovery.

An efficient, clean, atom-economical and simple method for the one-pot synthesis of novel spirooxindole derivatives via a three-component reaction of isatins, dimedone and anilinolactones was reported. This reaction was performed by using MnFe2O4 nanoparticles (5 mol%) as an efficient magnetically heterogeneous catalyst in water as green solvent. Prominent among the advantages of this method is the use of magnetically recoverable and reusable catalyst, simple work up procedure, good to high product yields and use of water as a solvent that is considered to be relatively environmentally benign.

Apart from a short introduction that describes biomass and its platform chemicals; this manuscript endevours to analyze and classify the enormous literature that has been generated for biomass conversion over a new class of heterogeneous catalysts metal?organic frameworks (MOFs); the recent progress of sugar conversion over MOFs based catalysis into valuable chemicals such as 5-hydroxymethylfurfural (5-HMF) and the subsequent secondary platform chemicals such as 2,5-dimethylfuran, ethyl levulinate and lactic acid was investigated. The smart selection of MOFs? building units and reaction solvents are critically discussed. The catalytic potential of different MOFs and composite MOFs was also investigated by demonstrating their remarkable performance with salutary examples relevant to biomass catalytic conversions into initial and secondary platform chemicals. This review also gives a state-of-the-art for the corresponding reaction kinetics and reaction mechanisms regarding the discussed sugar conversion.
