Meta-dimethylaminophenol and dimethylcarbamoyl chloride are esterified to obtain neostigmine base, and then methyl bromide is used to react to form a quaternary ammonium salt to obtain bromoxine Strytigmine. If the neostigmine base is reacted with dimethyl sulfate to form a quaternary ammonium salt, neostigmine methyl sulfate is produced.

Purpose

This product has a reversible cholinesterase inhibitory effect, resulting in acetylcholine not being enzymatically decomposed. It exists in cholinergic nerve endings for a long time and has the effect of exciting smooth muscle and skeletal muscles; it has a strong effect on skeletal muscles and has a small miotic force; it is mostly used for myasthenia gravis, postoperative abdominal distension and urinary retention, and can also be used for Detoxification of supraventricular paroxysmal tachycardia and tubocurarine overdose. Neostigmine methyl sulfate is for injection.

Properties and stability

Avoid contact with oxides.

Storage method

1. Store sealed in a cool, dry place. Make sure the workspace has good ventilation. Keep sealed.

2. Keep away from fire sources and store away from oxidants and acidic substances.

Synthesis method

1. Obtained from the reaction of diacetyl oxime and hydroxylamine-sodium sulfonate. Add diacetyl oxime to the hydroxylamine-sodium sulfonate solution, heat to 70°C, and keep warm for several hours to precipitate diacetyl oxime crystals. After cooling, filter immediately and wash with ice water until no more sulfate is contained. , that’s it. Hydroxylamine-sodium sulfonate can be prepared as follows: mix sodium nitrite with crushed ice, add a suspension of sodium bisulfite and water while stirring, then add glacial acetic acid from below the liquid surface while stirring, and then add Add concentrated hydrochloric acid and crushed ice to keep the reaction solution below 0°C. Use Congo red test paper to test for an acidic reaction. Filter to remove the insoluble precipitate to obtain a hydroxylamine-sodium sulfonate solution.

2.Add 70% sodium bisulfite suspension to 10% sodium nitrite ice water below 0°C under stirring In the mixture, stir continuously, add glacial acetic acid under the liquid surface, and then add a mixture of concentrated hydrochloric acid and crushed ice. During the reaction, add ice to control the temperature not to exceed 0°C. After the reaction, the solution is acidic to Congo red:

Filter out the insoluble matter to obtain an acidic solution of sodium hydroxysulfamate. Add diacetyl oxime to the above acidic solution, stir and heat to 70-80°C, maintain for more than 2 hours, let it stand, and filter after the crystallization is complete. Wash the crystals with water until neutral, spin dry and dissolve in ethanol, then add an appropriate amount of activated carbon for decolorization, evaporate, concentrate and dry to obtain white dimethylglyoxime crystals.

Purpose

1. Used for the verification and determination of nickel. Separate nickel from cobalt and other metals, and separate palladium from tin, gold, rhenium, iridium, etc. Photometric determination of cyanide, nickel, and palladium.

2.Spectrophotometric method for determination of chromogenic reagents such as nickel, weighing method for determination or precipitation separation of Ni2+ , Pd2+ and other precipitants. It can also be used as an extraction agent.

Purpose

Atropine is a parasympathetic nerve inhibitor that can be used as an eye dilator and laxative; it can relieve hay fever, cold nasal obstruction and intestinal spasm; it can be used to treat nocturia in children, and is sometimes used to relieve ureteral and bile duct spasm; and It can be used to treat poisoning caused by organophosphorus. As an anticholinergic drug, atropine’s various pharmacological effects are not conducive to its clinical application. Some substitutes with specific effects have been synthesized, such as homatropine as a pupil dilator. Atropine is highly toxic and can cause blurred vision, stasis of secretion, vasodilation, high fever, excitement, agitation and delirium when the dose is too high. It is an antagonist of morphine, pilocarpine, physostigmine, etc.

Biochemical research. A reagent for assaying gold.

Purpose

This product is used as a post-effect vulcanization accelerator for rubber and can also be used as a vulcanizing agent. When used as an accelerator, its performance in natural rubber is similar to that of the accelerator CZ (N-cyclohexyl-2-benzothiazole sulfenamide), but the delay is slightly greater. When used in 54.1 (W type) chloroprene rubber, it is equipped with the accelerator PZ (zinc dimethyldithiocarbamate), which can speed up the vulcanization speed, has good scorch performance, and has excellent physical properties of the product. When used in styrene-butadiene rubber, the scorch performance is poorer than the accelerator CZ. It can be combined with stearic acid to promote scorch and improve the tensile strength. When used as vulcanizing agent, it is advisable to add a small amount of thiuram or dithiocarbamate accelerator, which can increase the vulcanization speed and improve the aging resistance of the product. This product is easily dispersed in rubber and has almost no pollution. Mainly used in the manufacture of tires, inner tubes, rubber shoes, sponges, industrial products, etc. When used as a vulcanizing agent, the dosage is 2.5 to 5 parts, combined with about 1 part of accelerator PZ. When used as an accelerator, the general dosage is 0.4 to 1.5 parts.
