2-Butanone oxime Chemical Properties,Uses,Production

Oxime oxygen scavenger

Oxime compounds (dimethyl ketone oxime, methyl ethyl ketoxime (butanone oxime), acetaldehyde oxime) knows as a novel oxygen scavenger is disclosed in the U.S. and patented by Drew Chemical Company in 1984. It displays low toxicity, efficiency, fast-performance, and a blunt protective effects. In Europe and other developed countries it has been widely applied, and China it is also successfully developed in the nineties, and has been successful in promotion.
1. Oxygen scavenging performance: oxime compound is an organic compound with an oxime group. Oxime compounds are currently used for boiler shutdown protection and oxygen mainly acetaldehyde oxime, dimethyl ketone oxime (acetone oxime) and methyl ethyl ketone oxime. Oxime compounds have a strong reduction, easy to react with oxygen. When put in a wide temperature and pressure ranges, oximes has good oxygen scavenging performance. The optimum temperature range is 138~336 ℃, and pressure range is 0.3~13.7Mpa. According to comparative experiments, under the same conditions, the rate of oxygen and oxygen efficiency oximes is higher than that of hydrazine.
2. corrosion and passivation: oximes can restore high iron and copper oxide into suboxide, which can be a good solution in the steel magnetic oxide film formed on the surface of the metal surface passivation plays well, corrosion inhibition. Wherein dimethylketoximino is the best, using the minimum amount required. According to comparative experiments, oxime compounds having the same passivation, corrosion inhibition hydrazine, can significantly reduce the iron content in solution at high temperature and pressure conditions. The steel has a protective effect, among which the dimethylketoximino is best, which requires the least amount . Meanwhile, oxime compounds have cleaning actions to copper corrosion products deposited in the pipeline, economizer, etc., which is in the initial period of oximes. This is the reason why furnace copper water content is significantly higher.
3. Volatile: the volatile degree of oxime compounds is higher than that of hydrazine, DEHA, morpholine, cyclohexylamine, etc. It is close to the volatility of NH3. When the steam condenses, highly volatile oxygen scavenger will has a certain amount of condensation agent which is dissolved in water, therefore, helpful to protect the condensate system metal material.
4. decomposition: By experiments under the high temperature and pressure conditions, the decomposition products of oxime compound is NH3, N2, H2O, trace of acetic acid, formic acid produces, no adverse effects on water vapor system.
5. low toxicity: based on the data comparison of LD50, the LD50 for hydrazine is 290mg/kg, acetaldehyde oxime is 1900mg/kg, methyl ethyl ketone oxime is 2800mg/kg, dimethylket oximino 5500mg/kg. So the toxicity of hydrazine is very strong, and toxicity of oxime compound is very small. It belongs to low toxicity compounds. Test through the skin and mucous membrane contact with oxygen scavengers showed no significant oximes oxygen scavenger irritation and damage, but hydrazine causes damage of skin irritation, erosion, mucosal hyperemia.
