氨基磺酸厂家浅析连二亚硫酸钠的化学性质
来源:http://www.jnjrh.com 日期:2019-11-06 发布人:admin
  连二亚硫酸钠是一种遇湿易燃的化学物品,大家也经常会叫它为低亚硫酸钠,作为化学品是它会有什么共同的性质呢?下面氨基磺酸厂家--济南金日和化工给大家细致的引见一下。
  Even sodium bisulfite is a kind of wet and flammable chemical. We often call it sodium hyposulfite. What are its common properties as a chemical? The following sulfamic acid manufacturers -- Jinan jinrihe Chemical Co., Ltd. give you a detailed introduction.
  浅析连二亚硫酸钠的化学性质
  Chemical properties of sodium hydrosulfite
  连二亚硫酸钠的水溶液性质不稳定,有极强的复原性,属于强复原剂。暴露于空气中易吸收氧气而氧化,同时也易吸收潮气发热而蜕变,并能攫取空气中的氧结块并发出刺激性酸味。
氨基磺酸
  The aqueous solution of sodium hydrosulfite is unstable and has strong restorability, so it belongs to strong restorative agent. Exposed to the air, it is easy to absorb oxygen and oxidize, at the same time, it is also easy to absorb moisture and heat and metamorphosis, and it can grab oxygen lumps in the air and give off irritating sour taste.
  吸收空气中氧气的方程式:2Na2S2O4+O2+H2O=4NaHSO3或者Na2S2O4+O2+H2O=NaHSO3+NaHSO4
  Equation of oxygen absorption in air: 2na2s2o4 + O2 + H2O = 4nahso3 or Na2S2O4 + O2 + H2O = NaHSO3 + NaHSO4
  加热连二亚硫酸钠或接触明火会惹起熄灭,自燃点250℃。 与水接触能放出大量的热的二氧化硫气体和易燃的硫磺蒸气而惹起猛烈熄灭,遇氧化剂,少量水或吸收湿润空气能发热,惹起冒黄烟熄灭,以至爆炸。连二亚硫酸钠有毒,对眼睛、呼吸道黏膜有刺激性,连二亚硫酸钠普遍用于纺织工业的复原性染色、复原清洗、印花和脱色及用作丝、毛、尼龙等织物的漂白,由于它不含重金属,经漂白后的织物色泽非常鲜艳,不易退色。在各种物质方面,连二亚硫酸钠还可用于食品漂白,诸如明胶、蔗糖、蜜饯,及肥皂、动(植)物油、竹器、瓷土的漂白等。连二亚硫酸钠还可应用于有机合成,如染料、药品的消费里作复原剂或漂白剂,连二亚硫酸钠是zui合适木浆造纸的漂白剂。
  Heating with sodium bisulfite or contacting with open fire will cause the fire to go out, and the self ignition point is 250 ℃ Contact with water can release a large amount of hot sulfur dioxide gas and flammable sulfur vapor and cause violent extinction. In case of oxidant, a small amount of water or absorbed moist air can generate heat, cause yellow smoke to extinguish and even explode. Sodium hydrosulfite is toxic and irritating to eyes and respiratory mucosa. Sodium hydrosulfite is widely used in textile industry for restorative dyeing, restorative cleaning, printing and decolorization, as well as for bleaching of silk, wool, nylon and other fabrics. Because it does not contain heavy metals, the bleached fabrics are very bright in color and are not easy to fade. In terms of various substances, sodium hydrosulfite can also be used for food bleaching, such as gelatin, sucrose, preserves, soap, vegetable oil, bamboo ware, porcelain clay, etc. Sodium hydrosulfite can also be used in organic synthesis, such as the consumption of dyes and drugs as a restoring agent or bleaching agent. Sodium hydrosulfite is a suitable bleaching agent for Zui wood pulp and paper making.
