Research Progress on Application of Pro-Xylane in Cosmetics Industry
Effect of chlorambucil on potato subnormal germination and quality Abstract Pro-Xylane is a sugar-protein hybrid made from xylose with anti-aging activity, which can induce thebiosynthesis of glycosaminoglycans in the superficial epidermis of the skin, promote the regeneration of collagen, andis widely used in the cosmetics industry. In this paper, the preparation methods, biological activities and


The detection method of N-methylaniline
The detection method of N-methylaniline Abstract In this study, a gas chromatography/mass spectrometry (GC/MS) method was developed for the detection of N-methylaniline in textile products. N-methylaniline is an amine substance for which there is currently no detection method. However, the currently promulgated and implemented safety performance testing methods, especially footwear testing, have testing requirements for


Determination of Methylal and N-methylaniline in Motor Gasoline by Gas Chromatography
Effect of chlorambucil on potato subnormal germination and quality Abstract A external standard method for determination of illegal additives in gasoline by gas chromatography was developed,and methylal and N-methyl aniline were rapidly analyzed. results showed that,the calibration curves of illegal additives had the good linear relationship in the range of 0 ~ 4% ( V/V) .The recoveries


Effect of chlorambucil on potato subnormal germination and quality
Effect of chlorambucil on potato subnormal germination and quality Abstract To investigate the effects of isopropyl N-(3-chlorophenyl)carbamate(CIPC)treatment on sprouting and quality preservation of potato tubers during sub-ambient temperature storage at 12 ℃, the Favorita potato cultivar was chosen as the test material, and changes in germination and nutritional quality of potato tubers sprayed with 0.3


Synthesis of N , N’-di-sec-butyl-p-phenylenediamine antioxidant
Synthesis of N , N’-di-sec-butyl-p-phenylenediamine antioxidant Abstract N, N’-di-sec-buty l-p-phenylenediamine was synthesized using p-phenylenediamine, methyl ethyl ketone, and hydrogen as raw materials in the presence of Cu-Cr catalyst. The preparation conditions of the motivation and the effects of the reaction conditions, such as catalyst dosage, reacting temperature, pressure, and reaction time, on the yield of


Synthesis of Amines by Oxidative Coupling of Benzylamine over a Vanadium-Nitrogen Co-doped Porous Carbon Catalyst
Synthesis of Amines by Oxidative Coupling of Benzylamine over a Vanadium-Nitrogen Co-doped Porous Carbon Catalyst Abstract Synthesis of imine compounds via benzylamine oxidative coupling has become one of the most ideal methods due to its high atom economy and environmental friendliness. The key is to develop high performance non-noble metal-based heterogeneous catalysts. In this work,
