STUDIES ON FUMIGANT 'ETHYLENE OXIDE' (1). PROPERTIES OF MIXTURE OF ETHYLENE OXIDE AND METHYL BROMIDE
Abstract
Although ethylene oxide has long been known as an effective fungicidal and low boiling fumigant, use of this reagent alone is hazardous to the wide explosive region of two components system, air and ethylene oxide. In order to improve this, methyl bromide, which has the properties comparable to ethylene oxide and a high value as a fumigant, was mixed with ethylene oxide, and an experiment on their explosive properties was conducted. As a result, it was observed that methyl bromide narrowed the limit of explosion of ethylene oxide. Next, an experiment on the evaporation of ethylene oxide and methyl bromide mixture was conducted. Evaporation of inflammable methyl bromide was slightly faster than that of flammable ethylene oxide and the danger of filling the system with an explosive atmosphere of ethylene oxide, before the evaporation of inflammable reagent, is eliminated. Also, the polymerization of ethylene oxide is very much accelerated by addition of a certain type of chemical compound, and ethylene oxide loses its function. The addition of methyl bromide does not affect this reaction at all. The ethylene oxide and methyl bromide mixture system, therefore, is considered to have the superior properties as a fumigant.
