Molecular distillation is
|
|
High temperature distillation
|
|
|
For heat-sensitive materials
|
|
|
Very low pressure distillation
|
|
|
None of the above
|
Explanation:
Detailed explanation-1: -Molecular distillation is vacuum distillation below the pressure of 0.01 torr (1.3 Pa).
Detailed explanation-2: -Molecular distillation is a type of short-path vacuum distillation, characterized by an extremely low vacuum pressure, 0.01 torr or below, which is performed using a molecular still.
Detailed explanation-3: -This process is considered the safest means of separation for purifying thermally unstable substances with other related compounds that have elevated boiling point and low volatility. Molecular distillation is unique as it allows low(er) operating temperature, as a result of the vacuum within the distillation space.
