Title: Improvements in and relating to methods of preparing hydrocarbon-substituted silanes
IPC: C07F7/08
Filed: 1947-02-27
Abstract: Organo-silicon compounds of the general formula <FORM:0622323/IV (b)/1> wherein R and R1 represent alkyl, aryl, alkaryl, or aralkyl radicals, and n is an integer which is at least 1 and not greater than 3, are prepared by reacting a compound of the general formula (R1)nSiH(4-n) with a hydrocarbon lithium compound of the general formula LiR in the presence of a suitable liquid medium, i.e. liquid alkyl ethers, e.g. ethyl-n-propyl- or n-propyl-n-butyl ether, other types of ethers, e.g. diethyl ether of diethylene glycol or dioxane, and trialkyl substituted amines, e.g. triethyl-, tripropyl- or diethyl-methyl-amine, or mixtures thereof.  In examples, triethylpropylsilone is obtained by reacting triethylsilone and n-propyllithium, triethylbutylsilone from triethylsilone and n-butyllithium, and triethylphenylsilone from triethylsilone and phenyllithium.  A number of other substituted silones and hydrocarbon substituted lithium compounds that may be reacted are specified. Specification 575,667 is referred to.  The Specification as open to inspection under Sect. 91 refers to the use of any polar liquid medium for effecting the reaction. This subject-matter does not appear in the Specification as accepted.  Triethylsilone is prepared by reacting ethyldichlorosilone with an excess of the required amount of ethylmagnesium chloride.  The Specification as open to inspection under Sect. 91 refers to the introduction of other organic groups besides hydrocarbon groups by replacing hydrogen attached to silicon by the method given above, e.g., furyllithium or pyridyllithium may be reacted with triethylsilone to produce triethylfurylsilone or triethylpyridylsilone respectively.  This subject-matter does not appear in the Specification as accepted.

Abstract: 663,854. Discharge apparatus. SYLVANIA ELECTRIC PRODUCTS, Inc. Feb. 27, 1948 [Aug. 23, 1945], No. 6187/48. Class 39 (i). A cold - cathode gas - filled electric discharge tube comprises a cathode, a graphite electrode, and a lead-in wire extending into, but spaced and insulated from, said graphite electrode to act as an anode, the graphite electrode extending beyond the lead-in wire in a direction towards the cathode. In the tube 12, Fig. 2, the anode 14 is a tantalum wire attached to a metal cap 13 and supported by a glass tube 15 from which it is separated over the greater part of its length by an air-space 16, to prevent cracking due to heat. A graphite electrode 17, which may function as a control grid; is sealed to the glass tube 15 by heating the graphite to the softening point of glass and then pushing the glass tube into the graphite electrode, at the same time keeping the glass tube open by means of a mandrel. The graphite electrode is also. supported by a metal strip 18 attached to wires 19 supported in glass sleeves 20 from the press 29. The cathode (Fig. 3) comprises a " pill " 21 of caesium chloride and aluminium in a highly compressed form held in a nickel cup 22 insulated by a ceramic cup 24 'supporting an annular metal disc 25 which prevents sputtering of the cathode material and is provided with a lead-in wire 31 so that it may act as a keepalive electrode when necessary. A metal strap 27 masks the hole in the disc 25 to further prevent sputtered material from reaching the carbon electrode 17. A getter 28 is mounted on each side of the press 29. The filling may comprise helium at 7 to 20 mm. pressure, or any inert gas.
