Title: Process of producing vinyl ethers
IPC: C07C43/16
Filed: 1947-12-29
Abstract: Vinyl ethers are made by reacting acetylene at elevated temperature and pressure with a thermally and alkali stable mono-hydric phenol in non-explosive mixture in the presence of a catalyst comprising a mixture of an alkali metal hydroxide with zinc oxide or cadmium oxide.  Inert solvents may be present, preferably aromatic, hydroaromatic or aliphatic hydrocarbons liquid at 5 to 75 atmos. and 100-250 DEG  C.  Pressure is preferably used to maintain the ether formed in the liquid phase.  Preferably the ratios of oxide and hydroxide are in the molar proportions to form the corresponding zincate or cadmate.  Nitrogen is used as inert gas diluent and figures are provided showing the dilution of acetylene to give a non-explosive mixture and of apparatus for effecting the reaction. Temperatures of 150-250 DEG  C. and pressures of 100-1500 p.s.i. are preferred.  Acetals, e.g. acetaldehyde diphenyl acetal may be obtained as by-products. Vinyl phenyl-, vinyl-ortho-tolyl- and vinyl-3,5-xylyl ethers are made from the corresponding phenol. Specification 427,036 and U.S.A. Specifications 1,959,927 and 2,066,076 are referred to.

Patent GB-455181-A (GB)
Title: Improvements relating to the production of antimony oxide
IPC: C01G30/00
Filed: 1935-12-13
Abstract: <PICT:0455181/III/1> Antimony oxide is produced by treating a bath of lead-antimony alloy having an antimony content in excess of 40 per cent at a temperature of 1375--1500 DEG  F., with an oxidizing atmosphere, care being taken not to rupture the fluid mobile slag film which is formed on the surface of the bath.  Air or combustion gases containing free oxygen are used as the oxidizing gases.  An apparatus suitable for carrying out the process consists of a refractory-lined steel vessel 1 mounted on trunnions 5 and adapted to be tilted by worm gear 6.  A cast iron melting and fuming pot 4 is heated by a burner 7, a flue 10 being provided.  The pot is covered by a hood 11 provided with adjustable ventilators 12.  A cylinder 13 capable of vertical adjustment is arranged within the hood 11, and in use the lower edge is about nine inches from the surface of the melt. The antimony-lead alloy, or dross containing it which may contain impurities such as arsenic, copper, sulphur &c., but preferably not tin, is charged into the pot and melted. Bars of metallic antimony may be added if necessary.  Dross formed is removed exposing the thin mobile slag film.  Air is admitted gently through vents 12, the volatilizing antimony oxide being drawn off through flue 15. Periodically, a crust forming on the slag film is gently broken up and when necessary, removed by an iron skimming tool.  When the antimony content falls below 40 per cent, the pot is emptied.  A reverberatory furnace employing combustion gases containing free oxygen as the sweeping gas may be used in place of the apparatus shown.  A theory is put forward that the fluid slag film may consist of mixed oxides of lead and antimony which, by formation of higher oxides, act as an oxygen carrier to the antimony below the film.  The oxide may be used as an opacifying agent in enamelling or as a paint pigment. Specification 251,736, [Class 1 (iii)], is referred to.
