Patent GB-798444-A (GB)
Title: Process for the manufacture of heat stabilizing pastes for resinous compositions
IPC: C08K9/04
Filed: 1956-07-13
Abstract: A flushed paste having heat stabilizing properties for resinous compositions is prepared by agitating an aqueous filter cake of a basic lead salt with a water-immiscible organic vehicle in the presence of a minor proportion of a saturated or unsaturated, monobasic aliphatic carboxylic acid having 6-22 carbon atoms per molecule, thereby dispersing the basic lead salt in the organic vehicle, and separating the water portion.  The organic vehicle is preferably a plasticizer, e.g. dicapryl phthalate, di-iso-octyl phthalate, di-2-ethyl-hexyl phthalate, hexyl isodecyl phthalate, polyalcohol esters of adipic acid, polyglycols, triphenyl phosphate, and bis-(2-ethyl-hexyl)-2-ethyl-hexyl phosphonate; other suitable organic vehicles are mineral oil and petroleum jelly.  Basic lead salts specified are basic carbonate white lead, dibasic lead phthalate, dibasic lead phosphite, and tribasic lead sulphate. Suitable carboxylic acids are caproic, caprylic, lauric, capric, palmitic, stearic, undecylic, and behenic acids.  When using higher molecular weight acids, the transfer to the organic phase may be assisted by raising the temperature and/or by adding a small amount of a lower aliphatic alcohol.  Agitation may take place in a mixer having a vibratory or kneading action.  The flushed paste may be heated under vacuum to remove more of the water.  A flushed paste of white lead in mineral oil is also useful as a lubricant.

Title: Improvements in methods of preparing fluorine derivatives of hydrocarbons
IPC: C07C19/12
Filed: 1933-08-05
Abstract: The fluorination of acyclic hydrocarbons or their aryl derivatives by the action of hydrofluoric acid on a halogen derivative is effected in the presence of a catalyst consisting of carbon, such as charcoal or actuated, or acid-washed carbons.  The reaction may be effected in the vapour phase, but at least one of the reagents may be liquid; thus hydrofluoric acid is liquid at 80 DEG  C. at a pressure of 5--6 atmospheres.  A large number of initial materials are mentioned, including methylene chloride, fluoro-trichloro-methane, isopropyl bromide, tetrachlorethylene, benzotrichloride, benzodifluorochloride and benzotrichloride containing halogens in the nucleus.  The hydrofluoric acid may contain impurities such as water.  Examples describe the reaction in the vapour phase of hydrofluoric acid with carbon tetrachloride, chloroform, trifluorotrichloroethane, and symmetrical dichloroethane.  Those parts of the apparatus which come in contact with hydrogen halides may be formed of or lined with copper or monel metal.  Specifications 359,997 and 391,168 are referred to.  The Specification as open to inspection under Sect. 91 states that the initial halogenated hydrocarbon may be produced in situ by reacting the hydrocarbon with a chlorinating agent such as chlorine or antimony pentachloride.  The parts of the apparatus coming in contact with hydrogen halides may be formed of or lined with mild steel, chromium alloy steel, or molybdenum alloy steel. The following additional initial materials are mentioned, viz. ethyl bromide, bromoform, iodoform, difluorotetrachloro-ethane and benzotrichlorides with alkyl groups attached to the nucleus. This subject-matter does not appear in the Specification as accepted.
