Title: Preparation of 1,3-dichlorobutadiene-1,3
IPC: C07C67/00
Filed: 1971-07-21
Abstract: 1342536 1,3 - Dichlorobutadiene - 1,3 BP CHEMICALS INTERNATIONAL Ltd 21 July 1972 [10 Aug 1971] 37436/71 Heading C2C 1,3 - Dichlorobutadiene - 1,3 is prepared by chlorinating 1-chlorobutadiene-1,3 with gaseous Cl 2 , which may be diluted with a gas inert under the reaction conditions, (e.g. N 2 ), optionally isomerizing the chlorination product (a mixture comprising 1,1,4-trichlorobutene-2 and 1,3,4- trichlorobutene - 1) to form 1,3,4 - trichlorobutene-1 and subsequently dehydrochlorinating the chlorination product. The chlorination is preferably carried out at between - 50‹ and +500 C. and in the presence of a solvent (e.g. CHCl 3 , CCl 4 ) and a catalyst (e.g. a Lewis acid). The dehydrochlorination may be carried out in the presence of a base (e.g. aqueous NaOH) and a solvent (e.g. diethylene glycol ethyl ether). The optional isomerization is preferably effected at 50‹ to 180‹ C. at atmospheric or reduced pressure and in the presence of a catalyst (e.g. copper naphthenate). A polymerization inhibitor (e.g. t-butyl catechol) and an atmosphere of N 2 /NO mixture are advantageously present during the dehydrochlorination step which is, together with the chlorination, preferably effected in the absence of light.

Abstract: 1343888 Aircraft gas turbine engine thrust deflectors DEFENCE SECRETARY OF STATE FOR 1 Nov 1971 [6 Nov 1970] 52869/70 Heading B7G  Ducted fan turbine engine fan flow thrust deflecting apparatus comprises a double walled cowl having an aperture 36 within its length, an external wall portion 28 movable axially of the cowl, a plug 30 movable axially within the aperture 36 and a foldable inner wall portion 34 wherein, in a non-operative position (not shown) the foldable inner wall portion 34 forms an inner cowl wall to block the aperture 36, and the plug 30 and external wall portion nesting thereon together forming an outer cowl wall blocking the aperture 36 and wherein, in an operative position, said moveable external wall portion is moved to open a substantial portion of the aperture outer end and said blocker doors move to block the fan flow and deflects it through said aperture. In the operative position as shown, the cowl portion 28 is moved axially downstream clear of the aperture, the foldable inner wall portion 34 folding at the same time because of a link 42 with the cowl portion 28 to block a duct 48 between the cowl, which has fixed portions 22, 24 connected by struts 32 (one is shown), and the gas generator 12 of the engine, thereby blocking flow from a cold front fan of the gas turbine engine. With the plug 30 remaining in its inoperative position (solid lines) gas from the fan is entrained by air surrounding the cowl to flow rearwardly outside the cowl. However, when the plug 30 is moved fully upstream (dashed lines), the shape of the upstream edge of the aperture and the upstream edge of the plug 30 cause gas from the turbine to flow forwardly, adhering to the cowl casing by the Coanda effect, to provide reverse thrust. Movement of the plug to intermediate positions provides varying degrees of reverse thrust and forward thrust.
