The toluene diisocyanate has 2,4-toluene diisocyanates and 2,6-toluene diisocyanate (TDI).

There are two isomers of 2,4-toluene diisocyanate and 2,6-toluene diisocyanate (TDI). According to the content of the two isomers, there are three standard products in the industry: (1) TDI-65 contains 2,4-TDI65%, 2,6-TDI35%; (2) TDI-80 contains 2,4- TDI80%, 2,6-TDI20%, more common; (3) TDI-100 contains 2,4-TDI100%. Carbon dioxide occurs with water effect. Easy to work with compounds containing active hydrogen atoms. Linear polyurethane or polyurethane resin with diol effect.

HCFC-141b (monofluorodichloroethane) is a high-purity liquid widely used in cleaning and solvent fields.

Can gradually decompose, moist and high temperatures can accelerate decomposition. Can be decomposed by ethanol and silver ion.White crystalline powder.

The solubility in water was 549 g / L at 20 ° C. Relative density 2.400 (deposit density: 0.7).

N-butanol is an organic compound of the molecular formula C4H10O, which has a strong flame when the colorless transparent liquid is combined.

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.

A substance that can reduce the surface tension of water, solution, suspension, etc., prevent the formation of foam, or reduce or eliminate the original foam. [1]

Citric acid (CA), also known as citric acid, with the molecular formula C₆H₈O₇, is an important organic acid. It is colorless crystals, odorless, has a strong acid taste, is easily soluble in water, and is a natural preservative and food additive .

the crystal form of citric acid is exclusive due to distinctive crystallization conditions. it's miles barely weathered in dry air and hygroscopic in humid air. when heated, citric acid may be differentiated into diverse merchandise, that could react with acid, alkali, glycerin, and so on.

Lactic acid is a carboxylic acid, the molecular formula is C3H6O3, containing a hydroxyl group, belonging to α-hydroxyory (AHA). In an aqueous solution, the carboxyl group releases a proton to generate lactate ion CH3CH (OH) COO-.

Phosphorus pentachloride is mainly used as a chlorination reagent for alcohols, carboxylic acids, amides, aldehydes, ketones, enols, and Beckmann rearrangement reagents. It is used as a chlorination agent and catalyst in organic synthesis, and is used in the production of medicines, dyes, and chemical fibers. It is also the raw material for the production of phosphazene chloride and phosphorus oxychloride.

Acetic acid, also called acetic acid, glacial acetic acid, chemical CH3COOH, is an organic monovic acid, which is the main component of vinegar.
