Title: Chlorination of liquid phase of 1, 3- butadiene
Inventor: AREKUSANDAA TOMASU HARISU
IPC: B01J31/02
Filed: 1990-11-16
Abstract: PURPOSE: To obtain the subject compound in liquid phase chlorination at low temperature, by bringing 1,3-butadiene into contact with elemental chlorine in an evaporatively cooled reactor using a specific solvent under specific conditions, separating easily the unreacted feedstock and the solvent from the reaction product and reusing them.  
     CONSTITUTION: In the liquid phase chlorination of 1,3-butadiene to 3,4- dichlorobutene-1 and trans-1,4-dichlorobutene-2, the feedstock is brought into contact with elemental chlorine using a solvent comprising butane, pentane or a specific fluorinating solvent in a proportion of the solvent : dichlorobutene = 2.5:1-10:1, the solvent being inactive to the elemental chlorine under reaction conditions and having a boiling point of about -15-40°C at atmospheric pressure. The reaction is carried out in an evaporatively cooled reactor in the presence of a chlorination catalyst at about 25-100°C under a sufficient pressure to give the boiling point to the reaction mixture under atmosphere containing no oxygen. The unreacted feedstock and the solvent are separated easily and economically from the desired product, and recycled into the reaction system to give the objective compound at a low operation temperature in high yield with excellent specificity.

Filed: 1987-12-10
Abstract: PURPOSE:To attain the drive by a large current by connecting a circuit comprising a general-purpose operational amplifier and a current boost circuit to the operational amplifier of the first stage. CONSTITUTION:The output of the first stage amplifier IC 1 is connected to general-purpose operational amplifiers IC4, IC5 through resistors R9, R16. A signal from emitters of transistors(TRs) Q1, Q2 is given as an output through resistors R15, R16. This is a current boost circuit. The similar circuit constitution is applied to the current boost circuit for the IC 5. In case of current absorbing, an output of the operational amplifier IC 4 reaches -15V and a reverse voltage is applied to a diode D2, then it is turned off. Thus, a large current is absorbed from the point B to drive a ferrite polarizer. In case of current delivery, since the output of the operational amplifier reaches +15V conversely as above, a proper delivery is applied.
