Trimethylamine physical properties

Physical Processes foe Separating Metirylammes. Since the cost of separating methylamines is a major item, much effort has been put into developing separation processes. There are numerous patented separation procedures based on the differences in the phytical and chemical properties of these products. For example, Babcock found that the vapor-pressure curve of trimethylamine does not parallel the practically parallti curves of NH , mono- and dimethylamine. It intersects the dimethylamine curve at about 55 psia, and furthermore, when a mixture of trimethylamine and dimethylamine is distilled above this pressure, a dimethylamine-rich...
