Hydroxylamine hydrochloride powder Usage and Synthesis.

Hydroxylamine hydrochloride is an important organic chemical intermediate, which is mainly used in the preparation of oxime in organic synthesis reactions, such as the intermediate used in the pharmaceutical industry as neonomin, and the preparation of isatin intermediate in the synthetic dye industry. Because hydroxylamine hydrochloride has a good reducing effect, it is also often used as a reducing agent in industry, such as in the oil industry can be used as a fatty acid and soap antioxidant, antioxidant.

Uses of Hydroxylamine hydrochloride.

Hydroxylamine hydrochloride is an intermediate of carbamate oximide insecticides such as metocarb, aldicarb, dimetocarb sulfide, etc., and is also the raw material for preparing 2, 6-dichlorobenzonitrile and o-chlorobenoxime. As a reducing agent in the organic synthesis industry, the preparation of oxime is also used in the production of medicine, dyes, for color photography and film development and printing. In the synthetic rubber industry, it is used as a non-colored short-term stopper, in analytical chemistry for the examination of aldehydes and ketones organic compounds and trace analysis of sulfonic acid, in electrical analysis as a depolarizing agent, and in medicine for the production of neosomin, Danazol, ethinylestradiol, norethinone, methyltestosterone, hydroxyurea, librium, etc.

Hydroxyamine hydrochloride can be used as a reducing agent and a developing agent for color photography and film development.

​It is used as reducing agent in organic synthesis industry to prepare oximes, anticancer drugs and sulfonamides.

In medicine, it is also used in the production of neosomin, Danazol, ethinylestradiol, norethisterone, methyltestosterone, hydroxyurea, Librium and so on.

In the synthetic rubber industry, it is used as a non-colored short-term stopper.

In analytical chemistry, it is used for the examination of aldehydes and ketones organic compounds and the trace analysis of sulfonic acid, the determination of magnesium in steel, and the depolarizing agent in electrical analysis. It is also used in the production of dyes.

Preparation of Bulk Hydroxylamine hydrochloride powder.

Sodium nitrite reacts with sodium metabisulfite in water, acidifies with sulfuric acid, adds a certain amount of acetone, and neutralizes with liquid alkali. Acetone oxime is distilled, and acetone oxime is reacted with a certain proportion of hydrochloric acid to produce hydroxylamine hydrochloride and acetone. Hydroxyamine hydrochloride was produced by hydrolysis of nitromethane and hydrochloric acid.

Product Methods of Hydroxylamine hydrochloride.

1. Sodium nitrite synthesis (oximation method) add water to the reactor, stir and add sodium nitrite, add sodium metabisulfite in stages, and then acidize with sulfuric acid. The acidified material is sent to a hydrolysis kettle, acetone is added, and then neutralized with liquid alkali, and the neutralized liquid is distilled to obtain acetone oxime. Acetone oxime and hydrochloric acid were added to a salt kettle to produce hydroxylamine hydrochloride and acetone. Acetone recovery and use; Hydroxylamine hydrochloride is concentrated, cooled and crystallized, centrifuged and dried to obtain the finished product. Raw material consumption quota: sodium nitrite (95%) 1970kg/t, sodium metabisulfite (64% SO2) 5418kg/t, acetone (98%) 1175kg/t.

2. Nitromethane method Nitromethane reacts with hydrochloric acid and water to produce hydroxylamine hydrochloride. According to HGB3044-76, hydroxylamine hydrochloride products are white crystals, and the content of second grade products is ≥98.5, and the content of third grade products is ≥97%. Raw material consumption quota: nitromethane 1200kg/t, hydrochloric acid (30%) 1500kg/t.
