(1) Thus, an azeotrope can readily be distinguished from a compound.

(2) In order to separate n-hexane-ethyl acetate azeotrope , batch azeotropic distillation was often used and the entrainer played a key role in the process.

(3) Toluene is used as azeotrope in the preparation of ketal.

(4) The separation of azeotrope of methyl ethyl ketone water has been investigated by extractive distillation using the mixture of ethylene glycol and potassium acetate as an extractant.

(5) The advantages of heterogeneous batch distillation proccess make it widely used in separation of systems azeotrope.

(6) The experimental results showed that with the content of water was 7 % in the azeotrope mixture(/azeotrope.html), stigmasterol got the best selectivity.

(7) Such a constant - boiling solution is called an azeotrope.

(8) On this base, the suggestion is put forward on optimization of azeotrope tower operation adjustment to reduce the operation cost.

(9) Sodium phenolate and acetophenone can be obtained by adding sodium hydrate into azeotrope .

(10) Piperazine was separated from ethylenediamine byproduct polyethylene polyamines mixture by refrigeration and azeotrope distillation.

(11) Vapor - liquid equilibria and separation of methanol - dimethyl carbonate azeotrope are ( reviewed ) in this paper.
