The boiling point of 166 �ºC. Freezing point -20 �ºC. Relative density 0.9366. Refractive index 1.4380. Flash point 70�ºC (open cup).
Dimethylacetamide, the full name is N,N-dimethylacetamide (chemical formula: CH3C(O)N(CH3)2 abbreviated as DMAC or DMA. A commonly used aprotic polar solvent. Colorless Transparent liquid, flammable. Can be freely mixed with organic solvents such as water, alcohol, ether, ester, benzene, and aromatic compounds. Used in the preparation of drugs, synthetic resins, and also used as a solvent for polyacrylonitrile spinning and carbon Extractive distillation solvent for the separation of styrene in eight fractions, etc.
N-heptane is an organic compound with a chemical formula of C7H16. It is a colorless, transparent and volatile liquid, insoluble in water, soluble in ethanol and carbon tetrachloride, and miscible in ether, chloroform, acetone, and benzene. It is mainly used as Standards and solvents for determination of octane number can also be used in the preparation of organic synthesis and experimental reagents.
N-(n-butyl)-thiophosphoricTriamide(NBPT)
Urease inhibitors can inhibit the activity ofsoil urease, which can inhibit and slownitrogen release. The use of soil ureaseinhibitors can effectively slow down theprocess of urea decomposition intoammonia, reduce the concentration ofNH4+ and NH3 in the soil, reduce waste,and at the same time Extend the diffusiontime of nitrogen fertilizer at thefertilization point, so that the fertilizersupply of the soil and the fertilizerdemand of the crop are synchronizedThereby increasing the effective utilizationrate of nitrogen fertilizer by 30%-40%.
