In this article, denaturing with aniline and refining process of the oil responsible for toxic oil syndrome is briefly reviewed. The aspects considered include description of conditions of the main refining steps in relation to aniline derivatives formation, with special focus on the deodorization stage. In this last step of the refining process, an increase in the temperature, applied to such ...

Sodium dicyanamide NaC2N3 was found to undergo two phase transitions. According to thermal analysis and temperature-dependent X-ray powder diffractometry, the transition of alpha-NaC2N3 (1a) to beta-NaC2N3 (1b) occurs at 33 degrees C and is displacive. 1a crystallizes in the monoclinic system, space group P21/n (no. 14), with a = 647.7(1), b = 1494.8(3), c = 357.25(7) pm, beta = 93.496(1) degre...

refining oil-contaminated soils has a great importance especially in oil producer countries such as iran. different methods have been provided to eliminate oil contaminations from soil. the aim of this study was to investigate the effect of hydrogen peroxide concentration in refining oil-contaminated soils with fenton chemical method. to do this, a calcareous soil complex sample was collected a...

the aim of this research was optimization of refining of raw sugarcane juice using bentonite for production of natural liquid sugar or cane honey. non-sugar substances of raw sugarcan juice contains: colorants, polysaccharides, gums, proteins, etc that affect on efficiency and quality of the final product and should remove from raw sugarcane juice. gelatin is a protein which is used as an aid c...

rheological properties of chocolate are important in manufacturing process for obtaining high-quality products with well-defined texture and are directly influenced by composition and their refining time. soy protein benefits from nutritional and functional properties to be used in different foods. effects of different replacement levels of skim milk powder by soy flour, (from 0 to 100%) and ba...

The profiles of major volatile organic compound (VOC) sources in petrochemical industry of the Yangtze river delta, China, were experimentally determined. Source samples were taken using summa canister near the petrochemical units. The concentrations of 72 VOC species were quantified using canister sampling and a gas chromatography–mass spectrometry system, and VOC source profiles were develope...
