oxime oxygen scavenger Oxime compounds (dimethyl ketone oxime, methyl ethyl ketone oxime (butanone oxime), acetaldehyde oxime) as a new type of oxygen scavenger is the United States Drew chemical company patent published in 1984, with low toxicity, high efficiency, fast speed and passivation protection, in Europe, America, Japan and other developed countries has been widely used, china also developed successfully in the Nineties, and has been more successful promotion.
performance and application (1) oxygen scavenging performance: Oxime compounds are organic compounds with oxime groups, at present, the Oxime compounds used for boiler deaeration and protection mainly include acetaldehyde oxime, dimethyl ketone oxime (Acetone oxime) and methyl ethyl ketone oxime. Oxime compounds have strong reducibility and are easy to react with oxygen. Oxime compounds have good oxygen removal performance in a wide range of temperature and pressure, the most suitable temperature range is 138~336 ℃, the pressure range is 0.3~13.7Mpa. According to the comparative experiment, under the same conditions, the oxygen removal rate and oxygen removal efficiency of Oxime compounds are higher than that of hydrazine. (2) corrosion inhibition and passivation: Oxime compounds can reduce high-valent iron and copper oxides to low-valent oxides, and their aqueous solution can form a good magnetic oxide film on the surface of steel, it has good passivation and corrosion inhibition effect on metal surface. Among them, the effect of dimethyl ketone oxime is the best, and the amount required is the minimum. According to the comparative experiment, Oxime compounds have the same passivation and corrosion inhibition effect as hydrazine, which can significantly reduce the iron content in the solution, and have a protective effect on steel under high temperature and high pressure conditions, among them, the effect of dimethyl ketone oxime is the best, and the amount required is the minimum. At the same time, the Oxime compounds have a cleaning effect on the corrosion products of copper deposited in the pipeline, economizer and so on, which is also in the early stage of using Oxime compounds, the cause of the significant increase in copper content in the furnace water. (3) volatility: the volatility of Oxime compounds is higher than hydrazine, DEHA, morpholine, cyclohexylamine, etc, Close to the volatility of NH3. The highly volatile oxygen scavenger will dissolve a certain amount of the agent in the condensed water when the steam condenses, and thus, it is beneficial to protect the metal material of the condensed water system. (4) decomposition: Through the decomposition experiment under high temperature and high pressure conditions, the decomposition products of the Oxime compounds are NH3, N2, H2O, trace acetic acid, and no formic acid is produced, no adverse effects on the water vapor system. (5) low toxicity: according to the data of LD50, the LD50 of hydrazine is 290mg/kg, acetaldoxime is 1900mg/kg, methyl ethyl ketone oxime is 2800mg/kg, dimethyl ketone oxime is 5500mg/kg, it can be seen that hydrazine has strong toxicity, while Oxime compounds have little toxicity and belong to low toxicity compounds. Through the skin and mucosa contact test of oxygen scavenger, it is shown that oxime oxygen scavenger has no obvious irritation and damage, while hydrazine causes skin redness, erosion, mucosal hyperemia and other damage.
Application is mainly used for alkyd resin coating skin-proof agent and silicon curing agent. The product is used as an antioxidant for preventing skin formation, and the effect is better than that of butyraldehyde oxime and cyclohexanone oxime.
used in organic synthesis
used in various oil-based paint, alkyd paint, epoxy paint and other anti-skin treatment in the storage and transportation process, can also be used as Silicon curing agent
production method from the reaction of methyl ethyl ketone and hydroxylamine hydrochloride. It is also possible to react with hydroxylamine sulfate from butanone.
