Nitro is a concept in chemistry that refers to the group remaining after removing a hydroxyl group from the nitric acid molecule. A compound in which a nitro group is bonded to another group (mainly a hydrocarbon group) is called a nitro compound.

In the photocuring system, including UV glue, UV paint, UV ink, etc., after receiving or absorbing external energy, it undergoes chemical changes and decomposes into radicals or cations, thereby initiating polymerization.

Bromine is the only non-metallic element that exhibits a liquid state at room temperature and is one of six elements of the periodic table that are liquid at or near room temperature, a dark reddish brown fuming volatile liquid.

Chlorine is a non-metallic element and belongs to one of the halogens. Chlorine gas is yellow-green gas at normal temperature and pressure

Potassium sulphate is a colorless crystal, has low hygroscopicity, is not easy to agglomerate, has good physical properties, and is convenient to apply, and is a good water-soluble potassium fertilizer.

Potassium nitrate refers to a chemical fertilizer containing 13.8% nitrogen and 46.6% potassium oxide. Commonly known as fire nitrate or soil nitrate.

Magnesium hydroxide is an excellent flame retardant for plastics and rubber products. As a flue gas desulfurizer in environmental protection, it can replace caustic soda and lime as a neutralizing agent for acid-containing wastewater.

Sodium borohydride is stable at normal temperature and pressure, and the sodium borohydride alkaline solution is brownish yellow, one of the most commonly used reducing agents. It is stable to moisture and oxygen in the air

Hydrates refer to compounds containing water, which are quite broad in scope. The water may be linked to other moieties by a coordination bond, such as a hydrated metal ion, or a covalent bond, such as hydrated trichloroacetaldehyde.

Matrine is an alkaloid produced by extracting dried roots, plants and fruits of the leguminous plant Sophora flavescens by an organic solvent such as ethanol. The total alkaloids of Sophora flavescens L. is a general term for all alkaloids of Sophora flavescens.

The matrine pesticide used in agriculture actually refers to all the substances extracted from Sophora flavescens, called Sophora flavescens extract or Sophora flavescens total base. It is widely used in agriculture and has good control effect.

Nitrofurans are broad-spectrum antibiotics that kill most Gram-positive and Gram-negative bacteria, fungi, and protozoa.

Acetic acid, also known as acetic acid (36% - 38%), glacial acetic acid (98%), chemical formula CH3COOH, is an organic monobasic acid, which is the main component of vinegar.

Methane (the system name is “carbonane”, but it will only appear when introducing the system nomenclature. It is generally used in the natural name “methane”). It is widely distributed in nature. Methane is the simplest organic matter, natural gas, biogas, and gas.

Butylene (butylene, C4H8) has four isomers: 1-butene (CH3CH2CH=CH2); 2-butene (CH3CH=CHCH3), wherein 2-butene is further divided into cis and trans; CH3C(CH3)=CH2). The physical and chemical properties of the isomers of butene are basically similar.

Sodium ethoxide, also known as sodium ethoxide, sodium ethoxide, sodium ethoxide, has the chemical formula C2H5ONa and has a molecular weight of 68.05.
