Application: 2-Amino-2-methyl-1-propanol can form derivatives with carboxylic acid compounds for gas chromatography analysis; Can be used for the synthesis of surfactants, as vulcanization accelerators, acid gas absorbents, additives for coatings and latex paints, with pigment dispersion, pH adjustment, and rust prevention effects. Application: 2-Amino-2-methyl-1-propanol is mainly used as a biological stabilizer and pH stabilizer in the field of metal processing. This product is widely used in the concentration and post-treatment of metalworking fluids in Europe and America, and Chemicalbook is the main raw material for developing biostable formulas. Used in on-site replenishment to increase and stabilize pH values, rescue and prolong the life of metalworking fluids. This product also has advantages such as cobalt precipitation prevention and low foaming. Used for synthesizing surfactants; Vulcanization accelerator; Acidic gas absorbent. The production method involves reacting 2-nitropropane with an aqueous solution of formaldehyde, and then concentrating it into an aqueous solution containing 70% 2-methyl-2-nitro-1-propanol. Dilute with methanol to 30%. Add 5% by weight of nitro based skeletal nickel into the autoclave, and perform hydrogenation reduction at 30 ℃ and 267 atmospheres for 6-8 hours. After distilling methanol and most of the water under normal pressure, vacuum distillation is carried out to collect a 103 ℃ (8.53-8.67kPa) fraction, which is 2-amino-2-methyl-1-propanol. Based on 2-nitropropane, the yield is 70.5%.
