Abstract: Provided is a continuous process for preparing 1,1,2,3-tetrachloro-1-propene having the steps of catalytically dehydrochlorinating CH2ClCCl2CH2Cl in the gas phase to produce CHCl?CClCH2Cl; chlorinating the CHCl?CClCH2Cl to form CHCl2CCl2CH2Cl; and catalytically dehydrochlorinating the CHCl2CCl2CH2Cl in the gas phase to form CCl2?CClCH2Cl.

Abstract: Disclosed is a process for the synthesis of 1,3,3,3-tetrafluoropropene which comprises, in one embodiment, reacting a compound of CF3X1 with a compound of CX2H?CHX3, wherein X1, X2, and X3 are each independently selected from the group consisting of fluorine, chlorine, bromine and iodine, to produce a reaction product comprising a compound of CF3CH?CHX3, wherein X3 is as described above; and when X3 is not fluorine, fluorinating the compound to produce 1,3,3,3-tetrafluoropropene. The process in another embodiment comprises preparing tetrafluoropropene comprising thermally cracking one or more compounds capable of producing a reaction mixture which preferably comprises diflurocarbene radicals and vinylidene fluoride, and converting said reaction mixture into—tetrafluoropropene (1,3,3,3-tetrafluoropropene).

Abstract: In a puppet assembly, a head connector, upper limb connectors, and lower limb connectors are respectively coupled to an upper end, two sides, and a lower end of an inner layer of a puppet. The head connector is coupled with a head of the puppet in tight fit, and the upper and lower limb connectors are respectively coupled with upper and lower limbs of the puppet in tight fit, thereby permitting change of heads and upper and lower limbs of different forms for the puppet. The head connector has a lower end provided with an opening for extension of a finger to manipulate the head. The head connector and the upper and lower limb connectors have end portions provided with through holes to permit escape of air during assembly to the head or fitting into recesses in the upper and lower limbs to thereby facilitate assembly, and to permit extension of strings therethrough to permit manipulation of the head and the upper and lower limbs of the puppet.
