=FORMALDEHYDE ; =  _ Is a **STRONG** reducing agent in the present of akalis. _ Is **INCOMPATIBLE** with ammonia, alkalis, tannin, bisulfides, copper salts, iron salts, silver salts, iodine, potassium permanganate, and phenols. _ Can combine **DIRECTLY** with albumin, casin, gelatin, agar, and starch to form **insoluble** compounds. _ Reacts **VIOLENTLY** with nitrous oxides at about 180 C, mitromethane, manganese carbonate, hydrogen peroxide, and with strong oxidizers abd acids. _ Is produced **INDUSTRUALLY** by catalytic oxidation of methanol. _ Is a **COMMON** catalyst includes : silver metal or a mixture of an iron and molybdenum or vanadium oxides. _ Is found almost **EVERYWHERE**! _ 's lethal dose is 50. Pure Formaldehyde = 100 mg/kg Formalin (37% solution), which is fomaldehyde with water = 523 mg/kg _ Decomposition : **1**CH 2 O (g)->**1**CO(g) +**1**H 2 (g) _ Formaldehyde and another substance : **2** CH 2 OH + **1** O 2 → **2** CH 2 O + **2** H 2 O
