Title: Production of halo-fluoro derivatives of aliphatic hydrocarbons
IPC: C07C17/21
Filed: 1944-08-23
Abstract: 1,2-Dichloro-1,1-difluoroethane is produced by a process which comprises reacting trichloroethylene with hydrogen fluoride at a temperature of at least 100 DEG  C., preferably at between 150 DEG C. and 250 DEG  C., in the absence of a catalyst.  The ratio by weight of hydrogen fluoride to trichloroethylene may range from about 10 : 1 to about 1 : 5 and is preferably maintained between 2 : 1 and 1 : 2.  In one form of the invention illustrated by an example, a mixture of trichloroethylene and anhydrous hydrogen fluoride is heated in a high-pressure reaction vessel at about 200 DEG  C. until the reaction is substantially complete; the reaction vessel is then cooled and the pressure released through a water scrubber and the scrubber liquid added to the liquid contents of the reaction vessel. The crude product is separated from the water layer, washed, dried and distilled.  1,2-Dichloro-1,1-difluoroethane is useful as an intermediate for the preparation of fluorine containing compounds, for example, fluoro olefines which can be polymerized to form resins.

Title: New method of producing tubes or sleeves of cloth and appliance for carrying out said method
IPC: B01D39/08
Filed: 1954-06-01
Abstract: 758,880. Filters. JAUME, R. June 1, 1954 [June 2, 1953], No. 16195/54. Class 46. [Also in Groups V and XXII] In making cloth sleeves, which may be used as filters, undulations having the form of a part of the sleeve to be produced are formed in one of two pieces of cloth; the other piece of cloth, which may be flat or have undulations made in its complementary to those in the first cloth, is then superposed on the first and the two sheets united by applying a liquid or a band of liquefiable plastic material to the lines of contact of the undulations and allowing the liquid, or plastic material liquefied in situ by H.F. heating, to set in the meshes and finally cutting the cloth on both sides of each sleeve thus produced. In an example the cloth 11, which may be of metal, or of natural fibres, or of artificial fibres (such as vinyl chloride, polyamide, or superpolyamide), is laid on a die part 1 having semi-cylindrical recesses 3, Fig. 1, and cores 4 in supporting plate 5 placed over the cloth so as to make it conform closely to the recesses 3. A second piece of cloth 11a is then placed over the cores 4 and a top die 1a, complementary to the lower die 1, placed over the cores 4 and die 1 to complete the assembly. Plastic material is then run or injected through orifice 10 and channel 9 to fill grooves 8, 8a in the cores 4, thus permeating the cloth and forming internal ribs 12, 12a, Fig. 8, at the junctures of the superposed hemicylindrical sleeve parts. The sleeves may also have a part 14 closing one end and an external flange 15, which may be threaded externally or internally, at the other end, these parts being moulded at the same time as the ribs 12, 12a. The cloth is now cut to separate the attached sleeves. The ribs 12, 12a may be external, Fig. 11, by grooving the recesses 3, or may project outside and inside the sleeve in which case the grooves 8, 8a are both on the cores 4 and inside the recesses 3. The cross-section of the sleeve may be round, square or polygonal and the cores may be split so as to form a partition in the sleeve. In the case of a polygonal section one of the die sections may be flat; in an example a square sleeve is made with three sides formed by one cloth and the other side formed by the other cloth lying flat, four ribs then being formed, one at each corner, Fig. 15. The plastic material may be metal, a metal alloy, or a synthetic plastic, e.g. a polyamide.

Abstract: The invention comprises D 4-3,20-dioxo-11b , 18,21 - trihydroxypregnene, its 3,20 - bis - ethylene ketal, and a process for the preparation of steroids of the formula <FORM:0805609/IV (b)/1> in which R1 represents an aldehyde or carbinol group (the aldehyde group may be acetalized with the 11b -hydroxyl group) and R2 represents a free or esterified hydroxyl group, by treating a compound of the general formula <FORM:0805609/IV (b)/2> (in which X is a ketalized oxo group and Y is a free or esterified hydroxyl group) with a complex metal hydride in an inert solvent, and then liberating the ketalized oxo groups in positions 3 and 20.  The preferred reagent is lithium aluminium hydride in tetrahydrofuran or its mixture with dioxane or diethyl ether, and excess of the reagent yields an 11-hydroxy-13-carbinol whereas a quarter or third of a molar equivalent gives mainly the 11 : 18-semi-acetal, an additional quarter of a molar equivalent being required if a free 21-hydroxyl group is present.  In an example :-the 18 : 11-lactone of D 4 - 3,20 - dioxo - 11b ,21 - dihydroxy - pregnene - 18 - acid in ethylene dichloride is treated with ethylene glycol and p-toluene sulphonic acid and the resulting 3 : 20-bis-ethylene ketal reduced with lithium aluminium hydride in tetrahydrofuran to D 5-3,20-bis-ethylenedioxy-11b ,21 - dihydroxy - 18 - oxo pregnene, which on treatment overnight with 50 per cent acetic acid yields aldosterone; using excess reducing agent there is obtained the diketal of D 4-3,20-dioxo-11b , 18,21-trihydroxypregnene and subsequently the free 3,20-dione. Specifications 786,562 and 805,603 also are referred to.
