On June 25, 2016, Diogo, Joao C. F.; Avelino, Helena M. N. T.; Caetano, Fernando J. P.; Fareleira, Joao M. N. A.; Wakeham, William A. published an article.Quality Control of Tris(2-ethylhexyl) benzene-1,2,4-tricarboxylate The title of the article was Tris(2-ethylhexyl) trimellitate (TOTM) as a potential industrial reference fluid for viscosity at high temperatures and high pressures: New viscosity, density and surface tension measurements. And the article contained the following:

Tris(2-ethylhexyl) trimellitate (TOTM) was recently suggested as a reference fluid for industrial use associated with high viscosity at elevated temperature and pressure. Viscosity and d. data have already been published on one sample covering the temperature range (303-373) K and at pressures up to about 65 MPa. The viscosity covered a range from about (9 to 460) mPa s. In the present article we study several other characteristics of TOTM that must be available if it were to be adopted as a standard First, we present values for the viscosity and d. obtained with a different sample of TOTM to examine the important feature of consistency among different samples. Vibrating-wire viscosity measurements were performed at pressures from (5 to 100) MPa, along 6 isotherms between (303 and 373) K. D. measurements were carried out from (293 to 373) K up to 68 MPa, along 4 isotherms, using an Anton Paar DMA HP vibrating U-tube densimeter. Secondly, we report a study of the effect of water contamination on the viscosity of TOTM, performed using an Ubbelhode viscometer under atm. pressure. Finally, in order to support the use of TOTM as a reference liquid for the calibration of capillary viscometers, values of its surface tension, obtained by the pendant drop method, are provided. The experimental process involved the reaction of Tris(2-ethylhexyl) benzene-1,2,4-tricarboxylate(cas: 3319-31-1).Quality Control of Tris(2-ethylhexyl) benzene-1,2,4-tricarboxylate

An efficient green protocol for the synthesis of quinazolines in the absence of solvent and catalyst was developed. 2,4-disubstituted quinazolines were synthesized from three-component one-pot reactions of 2-aminoaryl ketones, orthoesters, and ammonium acetate. The present method had advantages of operational simplicity, substrate generality, clean reaction, high yields (76-94%), and moderate reaction time. The plausible mechanism of the reaction was proposed based on the spectral characterization and single crystal X-ray anal. of isolated intermediate.

Makuuchi, K.; Hagiwara, M. published an article in 1984, the title of the article was Radiation vulcanization of natural rubber latex with polyfunctional monomers – II.Reference of 2,2-Dimethylpropane-1,3-diyl bis(2-methylacrylate) And the article contains the following content:

Natural rubber latexes were vulcanized by γ-rays with 2 polyfunctional monomers, neopentyl glycol diacrylate (I) [2223-82-7] and neopentyl glycol dimethacrylate (II) [1985-51-9]. In comparison with I, II was more soluble in rubber particles, but it was less effective as an accelerating agent for the vulcanization because of the smaller rate of polymerization On the other hand, the colloidal stability of the latex containing I was low because it was localized on the surface of rubber particles due to its poor solubility in the particles. The solubility of I was improved by adding I with solvents. The maximum tensile strength of the irradiated latex film was 350 kg/cm2 at 3 Mrad. The experimental process involved the reaction of 2,2-Dimethylpropane-1,3-diyl bis(2-methylacrylate)(cas: 1985-51-9).Reference of 2,2-Dimethylpropane-1,3-diyl bis(2-methylacrylate)

Osawa, Tsutomu; Kizawa, Tomoko; Takano, Fumika; Ikeda, Shinji; Kitamura, Takayuki; Inoue, Yoshihisa; Borovkov, Victor published an article in 2014, the title of the article was Catalytic Enantiodifferentiating Hydrogenation with Commercial Nickel Powders Chirally Modified by Tartaric Acid and Sodium Bromide.Formula: C5H10O3 And the article contains the following content:

The chirally modified nickel catalysts for the enantiodifferentiating hydrogenation of β-ketoesters are prepared conventionally by immersing hydrogen-activated metallic nickel into an aqueous solution of enantiopure tartaric acid, in which the preactivation of nickel is essential. Herein, we revealed that even com. available nickel powders without any pretreatment can catalyze the enantiodifferentiating hydrogenation of β-ketoesters to give the corresponding β-hydroxyesters in quant. yield and high enantioselectivity (up to 91%) under optimized conditions. The immediate use of com. available nickel powders and the reproducible high chem. and optical yields not only expand the scope of heterogeneous asym. catalysis but also pave the way for the practical application and industrial use of chirally modified nickel catalysts. The experimental process involved the reaction of (R)-Methyl 3-hydroxybutanoate(cas: 3976-69-0).Formula: C5H10O3
