One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, Quality Control of Thymolphthalein, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 125-20-2, Name is Thymolphthalein, molecular formula is C28H30O4

Efficient lipid extraction is one of the main remaining challenges for full-scale production of biodiesel from urban sewage sludge, a low-cost feedstock. The common approach is to extract lipids from dewatered or dry sludge by means of organic solvents. However, sludge dewatering and drying are energy-consuming and represent more than 50% of the total production cost. Direct liquid-liquid extraction of lipids has been poorly explored; only extraction using hexane as solvent is described in the literature. This study focuses on the optimization of the extraction of lipids from wet raw urban sewage sludge at room temperature. This optimization is conducted varying solvent, pre-treatment, number of extraction steps, contact time and ratio sludge to solvent. The optimized method gives larger lipid amount (34.5%wt dry matter (DM)) than using hexane extraction (32.8%wt DM). Finally, the potential of lipid fractions extracted from eight sludge samples for biodiesel production was evaluated through the determination of acid value and free fatty acid (FFA) content, saponification number and fatty acid composition.

Copper-catalyzed N-arylation of diazoles can be accomplished using air-stable CuI as a copper source and 1,10-phenanthroline in the presence of KF/Al2O3 as a base. This is a simple and efficient method for the coupling of aryl bromide with diazoles. Different functionalized aryl bromides were coupled with diazoles using this system.

Related Products of 41717-32-2, 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, 41717-32-2, 1-Benzofuran-2-carbonitrile, introducing its new discovery.

Several heteroarenecarbonitriles (5) were synthesized in moderate yields from heteroarenes (3) through metalation, followed by electrophilic cyanation using p-toluenesulfonyl cyanide. Similarly, trimethylsilylheteroarenes (8) were converted to heteroarenecarbonitriles (5) in good yields by treatment with p-toluenesulfonyl cyanide.

Tuberculosis (TB) remains one of the leading causes of mortality and morbidity worldwide, with approximately one-third of the world’s population infected with latent TB. This is further aggravated by HIV coinfection and the emergence of multidrug- and extensively drug-resistant (MDR and XDR, respectively) TB; hence the quest for highly effective antitubercular drugs with novel modes of action is imperative. We report herein the discovery of an indole-2-carboxamide analogue, 3, as a highly potent antitubercular agent, and the subsequent chemical modifications aimed at establishing a preliminary body of structure-activity relationships (SARs). These efforts led to the identification of three molecules (12-14) possessing an exceptional activity in the low nanomolar range against actively replicating Mycobacterium tuberculosis, with minimum inhibitory concentration (MIC) values lower than those of the most prominent antitubercular agents currently in use. These compounds were also devoid of apparent toxicity to Vero cells. Importantly, compound 12 was found to be active against the tested XDR-TB strains and orally active in the serum inhibition titration assay.

Indolocarbazole glycosides are balanced between two conformations: a “closed” conformation containing a cyclic hydrogen bond between the indolocarbazole NH and the pyranose oxygen and an “open” conformation in which the indolocarbazole NH is hydrogen bonded to solvent. The open conformation never has a commanding advantage, even in DMSO, but in nonpolar environments the cyclic conformation predominates.

The constant growth in generation of waste printed circuit boards (WPCB) poses a huge disposal problem because they consist of a heterogeneous mixture of organic and metallic chemicals as well as glass fiber. Also the presence of heavy metals, such as Pb and Cd turns this scrap into hazardous waste. Therefore, recycling of WPCB is an important subject not only from the recovery of valuable materials but also from the treatment of waste. The aim of this study was to present a recycling process without negative impact to the environment as an alternative for recycling WPCB. In this work, a process technology containing vacuum pyrolysis and mechanical processing was employed to recycle WPCB. At the first stage of this work, the WPCB was pyrolyzed under vacuum in a self-made batch pilot-scale fixed bed reactor to recycle organic resins contained in the WPCB. By vacuum pyrolysis the organic matter was decomposed to gases and liquids which could be used as fuels or chemical material resources, however, the inorganic WPCB matter was left unaltered as solid residues. At the second stage, the residues obtained at the first stage were investigated to separate and recover the copper through mechanical processing such as crushing, screening, and gravity separation. The copper grade of 99.50% with recovery of 99.86% based on the whole WPCB was obtained. And the glass fiber could be obtained by calcinations in a muffle furnace at 600. C for 10. min. This study had demonstrated the feasibility of vacuum pyrolysis and mechanical processing for recycling WPCB.

A general method for the synthesis of phthalaldehydic acids and phthalides, many of which are key intermediates in natural product synthesis, has been developed. o-Bromobenzaldehydes 1a-f were first protected in situ as alpha-morpholinoalkoxides by reaction with lithium morpholide.Treatment of the alpha-morpholinoalkoxides 3a-f with n-butyllithium (to exchange bromine with lithium) followed by sequential treatment with solid CO2 and dilute acid afforded the phthalaldehydic acids 6a-f, respectively.Reduction of 6a-f with NaBH4 in EtOH furnished the phthalides 7a-f, respectively, in nearly quantitative yields.Efficient methods for the synthesis of the o-bromobenzaldehydes 1a-d, which were not readily available, are also described.
