Embodiment 1

[0024] The preliminary purification of ethanol solution, concrete steps are as follows:

[0025] Add 39.5g of ammonium sulfate in 100g of ethanol solution with a concentration of 24% (w / w), fully stir to make it dissolve; the lower phase is removed, and the upper phase solution has an ethanol concentration of about 57% (w / w) .

[0026] The high-concentration purification of ethanol solution, the specific steps are as follows:

[0027] Add 55g of ammonium citrate per 100g into the upper phase solution, fully stir to dissolve it, remove the lower phase, and the concentration of ethanol in the upper phase is about 90%.

Embodiment 2

[0029] To purify ethanol from low concentration to high concentration, the specific steps are as follows:

[0030] Add 39g of ammonium sulfate in 100g of ethanol solution with a concentration of 25% (w / w), ultrasonically dissolve it, transfer to the separatory funnel to discharge the lower phase, add 50g of ammonium citrate per 100g in the upper phase, and mix well It was dissolved, and the lower phase was discharged, and the ethanol concentration of the upper phase was about 88%.

Embodiment 3

[0032] The purification method from lower concentration to high concentration, the specific steps are as follows:

[0033] Be that the ammonium sulfate of 40g is added in the ethanol solution of 23% in 100g concentration, ultrasonic treatment makes it dissolve, transfer to separatory funnel and discharge lower phase, obtain upper phase liquid, ethanol concentration is about 56% (w / w), press again Add 45g of citric acid to every 100g of the upper phase liquid, mix well, separate the lower phase after standing to separate the layers to obtain the upper phase. According to scheme 2, high-concentration ethanol can be obtained by further separation.

Abstract

The invention relates to a distillation-free concentration method for alcohol, which comprises the following steps: 1, adding ammonium sulfate in an alcohol solution with the concentration of 20 to 30 percent, dissolving the ammonium sulfate through fully agitating, standing for layering to obtain an upper-phase solution and a lower-phase solution, and then removing the lower-phase solution and collecting the upper-phase solution; and 2, adding ammonium citrate in the upper-phase solution, dissolving the upper-phase solution through fully agitating, standing for layering to obtain another upper-phase solution and another lower-phase solution, and then removing the lower-phase solution and collecting the upper-phase solution, so as to obtain concentrated alcohol. The method provided by the invention has the advantages of convenience in operation, simple process and quickness in separation; and the alcohol obtained through the method has high concentration and wide application, and is convenient for large-scale industrialized production.

Description

technical field [0001] The invention belongs to the field of ethanol concentration, in particular to a method for concentrating ethanol without distillation technology. Background technique [0002] Ethanol is one of the most basic industrial products, widely used in various industries, such as food, beverage, chemical, fuel, pharmaceutical and other fields. With the depletion of petroleum resources, ethanol is the most potential clean energy to replace petroleum. Ethanol can effectively improve the performance and quality of oil products, and reduce the emission of major pollutants such as carbon monoxide and hydrocarbons. It does not affect the driving performance of the car, and also reduces the emission of harmful gases. [0003] As a new type of clean fuel, ethanol gasoline is currently the focus of the development of renewable energy in the world. It is in line with my country's energy substitution strategy and the development direction of renewable energy. It is tec...
