    Notes: [Auszug] Where a large number of pots has to be treated, this method may be time-consuming, and in view of the physical properties of ethylene oxide (solubility in water and boiling point 12-5 C.) it was considered that a more speedy method could be developed. Essentially the method consists of making up ...
