甲醛(CH_2O)是一种具有强烈刺激性的无色气体,沸点-21℃,比重0.815,极易溶于水,可与水或醇任意混合。35～40％的甲醛水溶液称为福尔马林(Formalin,通常在甲醛水溶液中加8％的甲醇防止其聚合)。由于还原作用和与蛋白质的氨基酸结合,使蛋白质变性凝固,故常用作生物标本的防腐剂或消毒剂。在食用菌的栽培中,常用甲醛进行无菌室(箱)及菇房的空气消毒。但就目前情况,据了解每米~3空间消毒方法有:40％甲醛8毫升加5克高锰酸钾;40％甲醛10毫升加5
Formaldehyde (CH 2 O) is a strongly irritating, colorless gas with a boiling point of -21 ° C and a specific gravity of 0.815. It is very soluble in water and can be freely mixed with water or alcohol. Formalin, 35-40% aqueous solution of formaldehyde is usually polymerized by adding 8% methanol in aqueous formaldehyde solution. Due to the reduction and protein amino acid binding, the protein denaturing coagulation, it is often used as a biological specimen of preservatives or disinfectants. In the cultivation of edible fungi, formaldehyde commonly used for sterile room (box) and Gu Fang air disinfection. However, the current situation, it is understood that each meter ~ 3 space disinfection methods are: 40% formaldehyde 8 ml plus 5 g potassium permanganate; 40% formaldehyde 10 ml plus 5
