acetone oxime usage and synthesis

physical and chemical properties	acetone oxime (abbreviation dmko for short), also known as dimethyl ketone oxime, is a white flaky crystal at room temperature, relative density: 0.9113, melting point: 60 ℃, flash point: 47.2 ℃, boiling point: 134.8 ℃, toxicity ld50: 5500mg / kg. it is soluble in water and alcohol, ether and other solvents, saturated aqueous solubility is 25% (mass percentage), its aqueous solution is neutral, it hydrolyzes easily in dilute acid, can make potassium permanganate fading at room temperature. mainly used as chemical oxygen scavenger for industrial boiler feed water, compared with the traditional boiler chemical oxygen scavenger, it has characteristics of less dosage, high oxygen removal efficiency, non-toxic, pollution-free. it is the best drug for the outage protection and passivation treatment of subcritical boiler, also is the ideal products of substituted hydrazine and other traditional chemical oxygen scavengers in medium and high pressure boiler feed water. figure 1 the molecular structure of acetone oxime.
chemical reaction	acetone oxime has a strong reduction, it is easy to react with oxygen in water to reduce the dissolved oxygen content in water, reaction is as follows: 2c3h7no + o2 → 2c3h6co + n2o + h2o and 4 (ch3) 2c = n-oh + o2 → 4 (ch3) 2c = o + 2n2 + h2o meanwhile, acetoxime also reacts with the metal for passivation, reaction is as follows: 2c3h7no + 6fe2o3 → 2c3h6co + n2o + 4fe3o4 + h2o acetoxime can reduce the content of iron in the feed water, to prevent overheating of the metal pipe and corrosion damage of the boiler due to the formation of iron oxide deposits, while with the cleaning effect for copper corrosion products deposited on pipes, economizer, etc. this is the reason that in the early use of acetone oxime, the content of copper in boiler water will be significantly higher. decomposition products of acetoxime are mainly nitrogen and water, a small amount of formic acid, acetic acid, nitrogen oxides and so on. on the premise of ensuring oxygen removal effect, when the residual amount of dmko in feed water is controlled to be 5 ~ 40μg / l, the formic acid, acetic acid, cl-, so42 + was not detected in all tested samples of water vapor, at the same time no2- and no3- content of same samples were tested, are also not detected. therefore, there is no any adverse effects for the use of acetone oxime oxygen in vapor system.
