This product is used as the first choice anti-tuberculosis drug with high efficiency, low toxicity and low price. It is also used as electroplating additive and pharmaceutical intermediate. Isoniazid methane sulfonic acid can be produced by condensing nicotinamide and formaldehyde sodium bisulfite [13447-95-5]. Condenses with formaldehyde to form diisoniazid. This condensation reaction is more soluble and easier to proceed. Add formaldehyde to the isoniazid aqueous solution. mso-bidi-font-family: 宋体; mso-font-kerning: 1.0pt; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA “>℃Left and right reactions It only takes half an hour. The condensation of isoniazid and vanillic acid is also carried out in aqueous solution, and the reaction temperature is 95℃left and right, producing isoniazid. These isoniazid derivatives are anti-tuberculosis drugs . Among the isoniazids, isoniazid has the best effect. Isoniazid has a weaker effect on tuberculosis bacteria, but is less toxic to the nervous system and liver than isoniazid.

Properties and stability

1. It is slightly corrosive to metals. When water is present, it decomposes into highly corrosive hydrogen chloride. Light can accelerate this decomposition. The acidity of 1,2,3-trichloropropane that has been stored or recycled for a long time should be checked before use. Toxic gases are produced during pyrolysis or combustion, so contact with red-hot objects should be avoided.

2. When heated with solid potassium hydroxide, hydrogen chloride is removed, and the main product of the reaction is 1,3-dichloropropene and a small amount of 2,3-dichloropropene. It is heated under pressure with water or sodium bicarbonate aqueous solution in the presence of copper to generate glycerin.

3. Stability^[23] Stable

4. Incompatible substances^[24] Strong oxidizing agent, strong alkali

5. Conditions to avoid contact^[25] Moist air, light, heat

6. Polymerization hazard^[26] No polymerization

7. Decomposition products^[27] Hydrogen chloride

Storage method

Storage Precautions^[28] Store in a cool, ventilated warehouse. Keep away from fire and heat sources. Keep container tightly sealed. They should be stored separately from oxidants, alkalis, and food chemicals, and avoid mixed storage. Equipped with the appropriate variety and quantity of fire equipment. The storage area should be equipped with emergency release equipment and suitable containment materials.

Synthesis method

1. α-Propylene chloride chlorination method: Propylene is chlorinated at high temperature to obtain allyl chloride. After washing and separation, it is then chlorinated at low temperature and fractionated to obtain the finished product.

2. Dichloroisopropanol Law.

Purpose

1. Used to produce pesticides, organic synthesis, and gas chromatography comparison samples. Used as a paint stripper for varnishes and coatings, and a solvent for engine cleaning. It can also be used as a raw material for pesticides such as chlormequat and Oat Di No. 1.
