  • Method for separating butanol
    Patent number: 8766019
    Abstract: Disclosed is a method for separating butanol. The method uses hydrophobic macroporous polymer adsorbent to separate butanol in a mixed solution, and the process comprises the following steps: 1) using macroporous polymer adsorbent to adsorb butanol in a mixed solution; 2) desorbing butanol from macroporous polymer adsorbent. The method is simple; the separation time is short; the efficiency of butanol recovery is high; and the separating cost is low.

  • CRYSTALLIZATION PROCESS OF CYCLIC ADENOSINE 3',5'-MONOPHOSPHATE
    Publication number: 20130090466
    Abstract: Provided is a crystallization process of cyclic adenosine 3?,5?-monophosphate, which comprises the following steps: 1) reacting an aqueous solution of cyclic adenosine 3?,5?-monophosphate with a base to obtain a salt of cyclic adenosine 3?,5?-monophosphate; 2) reacting the cyclic adenosine 3?,5?-monophosphate salt solution obtained in step 1) with an acid to obtain cyclic adenosine 3?,5?-monophosphate; 3) keeping cyclic adenosine 3?,5?-monophosphate obtained in step 2) at 0-15° C.
