The PVA/CD membrane preferentially permeated 1-propanol rather than 2-propanol from their mixtures. In particular, a mixture of 10 wt.% 1-propanol concentration was concentrated to about 45 wt.% through the PVA/CD membrane. The permeation mechanism of propanol isomers through the PVA/CD membrane was discussed based on the solution–diffusion Jul 31, 2021 · Compounds having the same number and kinds of atoms are called isomers.\(^2\) Whereas only one stable substance is known corresponding to the formula \(CH_4\), thirty-five stable isomers have been prepared of the formula \(C_9H_{20}\). From this one may begin to sense the rich variety of organic chemistry, which leads to many problems - in .

1 propanol and 2 propanol are which isomers
