Car urea is an essential product for heavy-duty diesel vehicles to meet the National IV emission standards. Vehicle urea refers to an aqueous urea solution with a urea concentration of 32.5% and ultrapure water as the solvent. The raw materials are urea crystals and ultrapure water. For diesel vehicles such as heavy trucks and passenger cars to meet the National IV emission standards, a suitable SCR system must be selected for exhaust gas treatment, and this system must use urea solution to treat nitrogen oxides in the exhaust gas.

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 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. Generally, the concentration of lactic acid in the blood is from 1-2 mmol / L during non-exercise, and can rise to 20 mmol / L during intense exercise.

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.
