酒精存在于所有酒精類飲料、部分醫(yī)藥化工產品里，以及部分醫(yī)療和工業(yè)用途。正因為食用酒精在人們的生活中用途**廣，成分很復雜，所以國家管理嚴格、規(guī)范?？梢哉f，食用酒精本身沒安全問題。<br/> ——酒精的區(qū)別在于用途。<br/> 理論上，酒精本身并沒有區(qū)別，都是乙醇，區(qū)別在于酒精里其他物質和含量，同時根據酒精的用途，決定要不要排除所含的其他物質。譬如工業(yè)酒精，不是用于吃喝，就不用考慮食品安全，只要保證足夠的酒精濃度就行。所以，害人的甲醇，就沒必要提取出來。但是食用酒精就要盡量剔除甲醇，把含量壓低到標準范圍以內。<br/> ——酒精的價格差別很大。<br/> 工業(yè)酒精制備成本很低，價格也便宜，于食用級差著幾倍。***的價格，工業(yè)酒精1600元/噸，食用酒精8500元/噸。這個差價，就是酒精酒初期屢屢違法案發(fā)的動力源頭。一斤酒的材料成本還不到一塊錢，而且還是現(xiàn)在的價格，上世紀八、九十年代會更便宜。所以違法分子敢鋌而走險。<br/> </p><p style="text-indent:25px">新型清洗劑無害。碳氫清洗劑具有無害的特點是通過毒理試驗得出的。將碳氫清洗劑的吸入毒性、經口毒性和皮膚接觸毒性均為低毒，且不屬于致*物質，與汽油相比對清洗操作人員更安全，這是碳氫清洗劑可以作為清洗劑替代汽油的重要原因。不破壞環(huán)境。碳氫清洗劑中不含氯，對臭氧破壞系數(shù)為零。碳氫清洗劑可以自然降解，清洗廢液可以放入燃煤或燃油鍋爐中焚燒，焚燒生成物主要為CO2和水，對空氣沒有污染。具有價格優(yōu)勢。與汽油相比，碳氫清洗劑的沸點高，閃點低，且安全可靠。作為金屬清洗劑的一種，盡管碳氫清洗劑有諸多優(yōu)點，但是還是存在一定的缺點的。比如，較高的沸點可以減少清洗劑在儲存、運輸和使用過程中的揮發(fā)損耗，但也使清洗后工件的干燥速度**降低，使清洗劑的蒸餾再生變得困難。較低的閃點則提高了清洗、干燥和蒸餾再生中的防火要求。硫酸銅的安全濃度范圍小，水體的體積和給藥量務必計算準確。</p><div
