There are rewards for correct answers; everyone who participates gets a reward. Let’s grow and mature through these Q&A sessions. Brief answer: Reasons for unsatisfactory water solubility. When there are many water-insoluble or poorly water-soluble organic impurities in pure methanol (such as alkanes, alkenes, or higher alcohols), these impurities precipitate as gel-like particles, causing turbidity; this is what is referred to as unsatisfactory water solubility. Reason: (1) The amount of pre-condensate recovered is low, and the temperature control of the second condenser in the pre-tower is too low. ⑵ Anhydrous extraction ⑶: Insufficient yield of fusel oil.
When there are large amounts of water-insoluble or poorly water-soluble organic impurities (such as alkanes, alkenes, or higher alcohols) in pure methanol, these impurities precipitate as gel-like particles, causing turbidity; this is referred to as a failure in terms of water solubility. Reason: (1) The amount of pre-condensate recovered is low, and the temperature control of the second condenser in the pre-tower is too low. ⑵ Anhydrous extraction ⑶: Insufficient yield of fusel oil.
⑴ The yield of the pre-condensed reflux liquid is low, and the temperature control of the second condenser in the pre-tower is too low. ⑵ Anhydrous extraction ⑶: Insufficient yield of fusel oil.
