Methacrylic acid is colorless crystal or transparent liquid with pungent odor. Soluble in hot water, soluble in most organic solvents such as ethanol and ether. Easily polymerized into water-soluble polymers. Combustible, there is a danger of burning in case of high heat and open flame, and it can produce toxic gas when heated.

Generally speaking, when the energy of the arrangement cannot be satisfied with oxygen breathing, it is arranged that the oxygen that cannot be obtained may not satisfy the quick treatment of oxygen, the concentration of lactic acid will rise. In this case, the acetone dehydrogenase cannot be converted to acetyl coenzyme a, pyruvate start-up. In this case, if the lactate dehydrogenase does not reduce the reduction of pyruvic acid as lactic acid, the composition of triphosphate is inhibited.

The melting point is 13.5°C, the boiling point is 140.9°C, and the density (20/4°C) is 1.0611g/cm3. The chemical nature is lively. It is easy to polymerize in air and can be reduced to propionic acid by hydrogenation. Addition with hydrogen chloride generates 2-chloropropionic acid. Used in the preparation of acrylic resins and other organic synthesis. It is made by oxidation of acrolein or hydrolysis of acrylonitrile, or made by carbon monoxide, acetylene and water under the action of nickel catalyst.

The lactate dehydrogenase is converted to a left lactic acid during the fermentation process. Lactic acids are constantly occurring in general metabolism and motion, but its concentration generally does not rise. Only in the lactic acid occurs, lactic acid cannot be transported in time to increase. The lactic acid transport speed is affected by a series of factors, and includes a monocarboxy-dient, lactate dehydrogenase concentration and isomer form, and the oxidative capacity arranged.

Ricia oil contains a lot of ricic acid (more than 80%), so many unique properties:
1. It is easy to dissolve in ethanol, which is difficult to dissolve in petroleum ether. This feature is more likely to distinguish between castor oil from other grease.
2. The viscosity is much higher than that of the general oil, and 25 is 680 cps, the viscosity index 84, the friction coefficient is very low (0.1).
The fluidity of castor oil is good, and the refined castor oil can still flow in -22.

It uses oxygen with a purity of 93.5%-99.2% and combustible gas (such as acetylene) to produce a flame of extremely high temperature, thereby melting the metal. The metallurgical process cannot do without oxygen. In order to strengthen the production of nitric acid and sulfuric acid, oxygen is also required. Instead of using air, a mixture of oxygen and water vapor is blown into the coal gasifier to obtain coal gas with high calorific value.
