Sulfur, white and shiny crystal compounds. The taste is bitter, density is 1.405, and the melting point is 180 to 182 ° C. Decomposition when it is hotter, soluble in water, can be dissolved in ethanol when heating, and is slightly dissolved in ether. During the melting, heterogeneity is partialized to form ammonium thiocyanomylisocyanomylocyne. The raw materials used to make drugs, dyes, resins, and plastic powder, and are also used as a vulcanized promoter for rubber, flotal agents for metal minerals.

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.

Appearance and traits: white crystals, extremely salty, non -toxic. It is easy to solverate in water, ether, glycerin and alkali, slightly soluble in ethanol, but insoluble in water -free ethanol, which is hygroscopic and easy to lump; New potassium salt is generated by reciprocating and disintegrating.

White oblique crystals, industrial products are white or light gray lumps or rods. Easily soluble in water, emits a lot of heat of dissolution when dissolved, soluble in ethanol, slightly soluble in ether. It is deliquescent and has strong water absorption.
Potassium hydroxide is strongly alkaline and corrosive, and its properties are similar to sodium hydroxide, which can cause burns. It can absorb water and dissolve in the air, and absorb carbon dioxide to gradually become potassium carbonate. The pH of the 0.1 mol/L solution is 13.5.

TDI is the abbreviation of toluene diisocyanate. TDI is a polycyanate widely used in industrial production. It is a polyurethane material and an important basic material. Mainly used to make flexible polyurethane foam, polyurethane elastomer, coatings, adhesives, etc.
TDI (toluene diisocyanate) is one of the commonly used polyisocyanate, and polyisocyanate is an important base material of polyurethane (PU). The TDI commonly used in the polyurethane industry is a mixture of 2,4-TDI and 2,6-TDI isomers, including three commonly used grades.
Generally speaking, when the human body undergoes aerobic metabolism, glucose will be converted into pyruvate, which enters the tricarboxylic acid cycle to produce energy; at the same time, pyruvate produces lactic acid.
harmless. Nano-titanium dioxide is a stable metal compound with good stability.
It is necessary to reduce the harm of human beings. The best way is scientific application. Carbon dioxide actually has two sides. On the one hand, a greenhouse effect will be generated; on the other hand, it will benefit humanity, such as use as plant gas and fruit and vegetable prevention.
Titanium dioxide naturally exists in titanium ores such as titanium ore and rutile. Its molecular structure gives it high brightness and covering properties, but it must first be chemically extracted and purified. More than 60 years ago, DuPont invented the chlorinated titanium dioxide production process. Compared with the old sulfuric acid process, it can manufacture high-quality pigment products while reducing environmental emissions and Chemicalbook energy consumption.
Since the use of sodium nitrite in the bleach is due to its ability to form sulfur dioxide, sulfur dioxide has strong oxidation resistance, and color oxidation can be oxidized.
The principle of photocatalysis is based on the oxidation-discount capacity of photocatalysts beneath mild conditions, which can reap the purpose of purification of pollution, cloth synthesis and transformation. usually, the photocatalytic oxidation response makes use of a semiconductor as a catalyst and mild as an power source to degrade organic rely into carbon dioxide and water.
The appearance of potassium hydroxide is white lumps or powder, with strong corrosiveness and strong alkalinity. When potassium hydroxide is exposed to gas, it is easily wetted by moisture in the air, digesting and absorbing carbon dioxide to become potassium carbonate.
This product is a white powder with strong hygroscopicity. It is prone to deliquesce when exposed to the air and absorbs carbon dioxide to generate potassium carbonate.
