Method of preventing generation of heavy ingredient of methyl ethyl ketone |
| abstract |
A method of preventing the generation of a heavy ingredient of methyl ethyl ketone in which a dimerization-preventive material is used at least as that surface of a purification apparatus or storage apparatus (50) which is in contact with methyl ethyl ketone. The dimerization-preventive material for use in the purification apparatus preferably is stainless steel, while the dimerization-preventive material for use in the storage apparatus (50) preferably is zinc or aluminum. |
