Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -It has been reported that some derivatives of azo-liquid crystals have good inhibition efficiency as antioxidants. In this book , I aim to prepare some azo liquid crystal compounds and study their effect on the oxidation of lubricating base stocks. The effect of the concentration of these azo liquid crystalline compounds on the oxidation stability of the lubricant base oil will be studied. I18d liquid crystal (500ppm) was the best as an antioxidant. 132 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The oxidation stability of lubricating oil has critical influence on the oil performance during service. Oxidation stability is a chemical reaction that occurs with a combination of the lubricating oil and oxygen. The rate of oxidation is accelerated by high temperatures, water, acids and catalysts such as copper. The rate of oxidation increases with time. The service life of a lubricant is also reduced with increases in temperature. Oxidation will lead to an increase in the oil's viscosity and deposits of varnish and sludge. So,used new organic compound as antioxidant for lubricating oil. 140 pp. Englisch.…
