Cyclohexylamine, an organic compound with chemical formula of C6H13N, is a colorless to yellow liquid, soluble in water, miscible with most organic solvents, mainly used as a solvent, but also used to produce desulfurizer, rubber antioxidant, vulcanization accelerator, plastic and textile chemical additives, boiler water treatment agent, metal corrosion inhibitor, emulsifier, preservative, antistatic agent, latex coagulant, petroleum additive, bactericide Pesticides and dye intermediates. What should we pay attention to when packaging and transporting cyclohexylamine?
(1)包裝

儲于陰涼、通風(fēng)倉間內(nèi),遠(yuǎn)離熱源,防止陽光直射;應(yīng)與氧化劑分開存放;倉間照明、通風(fēng)等應(yīng)采用防爆型,并應(yīng)有防火防爆技術(shù)措施;充裝時應(yīng)注意控制流速,并禁止使用能產(chǎn)生火花的工具和機(jī)械。
Store in a cool and ventilated warehouse, away from heat sources and direct sunlight; It shall be stored separately from oxidant; The lighting and ventilation in the warehouse shall be explosion-proof type, and shall be provided with fire and explosion protection technical measures; During filling, pay attention to control the flow rate, and prohibit the use of tools and machinery that can produce sparks.
(3)用途
(3) Purpose
pH值調(diào)節(jié)劑,用于鍋爐給水的pH值調(diào)節(jié)。定期使用除垢劑可使設(shè)備無垢運(yùn)行。
PH regulator is used for pH adjustment of boiler feed water. Regular use of scale remover can make the equipment operate without scale.
環(huán)己胺溶于水中呈堿性,因而可以中和水中的游離二氧化碳,提高給水pH值,減緩二氧化碳腐蝕。與氨相比,環(huán)己胺有兩個特點(diǎn):一,分配系數(shù)較小。據(jù)有關(guān)文獻(xiàn)的數(shù)據(jù),在蒸汽壓力為0.2~1.0MPa所對應(yīng)的飽和溫度范圍內(nèi),氨的分配系數(shù)為7~10,而環(huán)己胺的則為2?4。
Cyclohexylamine is alkaline when dissolved in water, so it can neutralize the free carbon dioxide in water, improve the pH value of feed water and slow down the carbon dioxide corrosion. Compared with ammonia, cyclohexylamine has two characteristics: first, its distribution coefficient is small. According to the data of relevant literature, within the saturation temperature range corresponding to the steam pressure of 0.2~1.0MPa, the distribution coefficient of ammonia is 7~10, while that of cyclohexylamine is 2? 4。
分配系數(shù)小,則表示在液相中環(huán)己胺的濃度比氣相中的高,即其水溶液的堿性(也即中和水中游離二氧化碳的能力),環(huán)己胺弱于氨;二,對于高參數(shù)機(jī)組而言,加入環(huán)己胺應(yīng)考慮其在溫度超過510℃的條件下,在蒸汽中可能發(fā)生分解的問題。
If the distribution coefficient is small, it means that the concentration of cyclohexylamine in the liquid phase is higher than that in the gas phase, that is, its aqueous solution is alkaline (that is, its ability to neutralize free carbon dioxide in water), and cyclohexylamine is weaker than ammonia; 2、 For high parameter units, cyclohexylamine may decompose in steam when the temperature exceeds 510 ℃.
Because of this, at present, cyclohexylamine treatment is mainly used for feed water treatment of medium and low pressure boilers. Regular use of scale remover can make the equipment operate without scale. Come to our website for more relevant content http://www.laiyanglicheng.com consulting service
