Title: Polymerisation of n-vinylcarbazole
Inventor: ELLINGER LEO PHILIPP
IPC: C08F26/12
Filed: 1963-08-24
Abstract: The polymerization of N-vinyl carbazole is effected in the presence as initiator of at least one organic compound which is electrophilic with respect to the monomer, but which under the conditions of polymerization is not a sufficiently strong electron acceptor to form a stable anion.  Polymerization can be carried out in bulk or in solution at temperatures from ambient to 120 DEG  C. The initiators fall into various classes:  (1) quinoid compounds, e.g. quinine, chlorocinil, and also maleic anhydride; (2) aromatic polynitro compounds; (3) tetranitromethane; (4) ethylene compounds in which at least one of the hydrogen atoms is substituted by an electron-attacking substituent. The examples relate to the use of maleic anhydride, chlorocinil, tetra cyano ethylene, 1,3,4 - trinitrobenzene, trichloromethylene, tetrachloroethylene, acrylonitrile, methyl methacrylate.

Title: Improvements in the removal of substances forming resins from benzines which are to be employed as motor fuels
IPC: C10G29/12
Filed: 1932-11-28
Abstract: Benzine is freed from gum-forming constituents without removal of valuable unsaturateds by treating with (1) a polymerizing agent under conditions too mild to polymerize all the gumforming bodies; and (2) either before or after (1) with silent electric discharges under nonoxidizing conditions.  The oil may finally be treated with bleaching earth or other adsorbent, and distilled. Polymerizing agents specified are sulphuric acid, iron chloride, aluminium chloride, and the double compound of aluminium chloride with ethylene or other gaseous olefine.  The milder conditions are obtained by reducing the percentage of polymerizing agent used and the temperature and duration of treatment.  For example, cracking benzine boiling up to 200 DEG  C. is treated with 1 per cent of aluminium chloride at 60--70 DEG  C., then exposed for 3 hours at room temperature and may be in an atmosphere of hydrogen or inert gas to high voltage alternating current produced by a Tesla transformer, and afterwards mixed with bleaching earth and distilled.  Direct current of 30,000 volts for 5 min., or alternating current of 220 volts and 50 Hertz for 16 hours may be used.  Crude products, e.g. crude cracked oils may be treated.
