Rectification tower is essence of life takes one of main facility that involve in craft, it can finish all sorts of different rectification techniques, include constant boil rectify, often press rectification, intermittent rectify to wait a moment, corresponding also is need not the product is made take. Wanting those who remind everybody is, if want preparation pure alcohol, cannot use constant boil rectify, what reason is this?
Because alcohol and water can be formed,basically be in all boil content, its constant boiling point is 78.15 ¡æ , with the boiling point of alcohol 78.3 ¡æ are close to very, be in so often press next methods that use convention detached alcohol – aqueous solution, tall can get chroma is the alcohol of 95.57% only. Such word, purity cannot rise after arriving at this one purity through constant boil rectify. If add constant boil agent, if rectify of the boil that use constant reacts, also can get anhydrous alcohol only, is not pure alcohol.
