Title: Method of producing organic cyclic perfluoroethers having 5 or 6-membered rings
IPC: C07D307/18
Filed: 1959-08-08
Abstract: Organic cyclic per-fluoro ethers of 5- or 6- membered rings are made by electrolysis of an aliphatic carboxylic acid halide mixed with anhydrous H.F. e.g. butyryl or capronyl chloride. The electrolysis is effected at low temperatures and the products condensed fractionally to remove HF, and isolate the products. In examples, butyryl chloride and a little sodium fluoride is dissolved in anhydrous HF and submitted to electrolysis at - 20 C. at 5.5 to 6 V., further butyryl chloride being added as the reaction proceeds. The products are condensed at - 70 C. and surplus HF returned to the cell. About 31% of the acid chloride is converted to perfluorotetrahydrofurane. The production of perfluorostitia hydro pyranes from branched chain acid chlorides is also referred to.

Title: Preparation of phthalic acids by oxidation
IPC: C07C51/265
Filed: 1959-07-21
Abstract: <PICT:0864106/IV (b)/1> An oxidation process for the production of phthalic acids and esters comprises continuously introducing a xylene and a lower alkyl toluate into the first of a series of oxidation zones, continuously oxidising said xylene and said alkyl toluate in said zone in the liquid phase by passing an oxygen-containing gas p therethrough, continuously withdrawing oxidate containing unreacted alkyl toluate from said first zone, passing said withdrawn oxidate to a second oxidation zone while simultaneously introducing additional xylene to said second zone, continuing the oxidation of said withdrawn oxidate in the presence of said additional xylene in said second oxidation zone in the liquid phase by passing an oxygen-containing gas therethrough and continuously withdrawing oxidate containing a monoalkyl phthalate and a phthalic acid from said second oxidation zone, the amount of xylene introduced into each oxidation zone being proportioned to provide approximately equal rates of oxidation in each zone, in terms of acid number increase per hour, and the total amount of xylene introduced being in excess of that stoichiometrically equivalent to the amount of lower alkyl toluate introduced in the process. The terms "phthalic acid," "toluic acid" and "xylene" are intended to include all the various isomers and the term "lower alkyl" is defined as containing 1 to 4 carbon atoms. The oxidation may be carried out at 120-230 DEG C. and at elevated pressure in the presence of an oxidation catalyst e.g. cobalt toluate using air as the oxidising gas. In a preferred embodiment illustrated in Fig. 2 alkyl toluate is introduced into oxidiser No. 1 through A, residue from previous oxidations e.g. partially oxidised xylenes and toluates, is introduced through B, catalyst is introduced through C and the off gases from oxidiser No. 2 containing both oxygen and xylene are introduced through E. The oxidate is withdrawn from oxidiser No. 1 and passed to oxidiser No. 2 through D and additional xylene simultaneously introduced through F. The oxidate is withdrawn through G, unreacted xylene removed in the xylene stripper and the stripped oxidate esterified and then distilled to give an alkyl toluate which is recycled, a dialkyl phthalate and a high boiling residue. In examples p-xylene and methyl p-toluate are oxidised and the stripped oxidate esterified with methanol. Specification 809,730 is referred to.

Patent ES-357783-A1 (ES)
Title: Manufacture of a multicomponent polymeric product
IPC: D01D1/06
Filed: 1968-09-02
Abstract: Filament yarn, thread, film or sheet products consisting of a basic mass with embedded therein a large number of endless threads are produced by a process in which at least two substantially synthetic liquid polymer components such as nylon 6 polyamide and polyethylene terephthalate are placed side by-side to form a single main stream which is repeatedly divided and multiplied to form a multi-layer structure and is then extruded through a die, e.g. a spinneret plate or a casting slit, in which process prior to the main stream being extruded at least a second multi-layer structure is superposed on the first, the layers of the second structure being at an angle of at least 10 degrees to the first multi-layer structure. Preferably, the second multi-layer structure is formed by passing the multi-layer stream through a second mixer in which it is again repeatedly divided and multiplied. The number of layers in the two structures may be different. The film thickness may be from 10 to 100Á but sheets having a thickness of from 0À75 mm. to a few millimetres, in which there extend endless threads having a thickness of from 0À200 to 0À500 mm. can also be made. Yarns may be made from the film by dividing into a large number of ribbons which extend in the longitudinal direction of the film, or by removing the basic mass either entirely or partially from the film, sheet or ribbons, e.g. with a solvent or by a heat treatment. The cross-sectional shape of each of the threads or filaments may be different from that of the extrusion orifice(s), and is uniform along the length. The yarn or thread extruded through a die or a spinneret plate in which there are one or more circular spinning orifices may have a non-circular cross-sectional shape which may be triangular, polygonal, bean-shaped, ribbonshaped, or tri- or multilobal shape. In a particular embodiment the apparatus for spinning monofilaments is at least provided with a feed system for the side-by-side supply of two or more polymer liquids, and a main channel 7 in which the liquids join, and located in the main channel 7, a mixer 8 with stationary guiding members in which the liquids may be repeatedly divided to form a multi-layer structure and a spinneret plate 23 with a single circular orifice 24, in which contiguous to the initial mixer 8 there is at least a second mixer 9 of the same type, which is turned on its longitudinal axis through an angle of at least 10 degrees to the first mixer. The apparatus for casting a film is similar to the above except that the spinneret plate 23 is replaced by a casting slit. For spinning a yarn, a spinneret plate containing a large number of circular orifices is used. Filaments or yarns with a non-circular cross-section are produced when the distance between the second mixer 9 and the spinneret plate with the circular orifice(s) is relatively small. When the distance is relatively large, circular cross-sections result.

Title: Late process for increasing the molecular weight of polyethylene terephtha
IPC: C08G63/80
Filed: 1969-05-09
Abstract: The molecular weight of polyethylene terephthalate is increased by heating granules of the polyester of solution viscosity 1À4 to 2À3 to a maximum temperature of 210-240 C. in a stabilized stream of a bulk layer which is moving under gravity alone and which has an inert gas passed countercurrent to it, thus after-condensation being continued until the solution viscosity is 1À6 to 3À0. The granulate used suitably has an average degree of crystallization of 30-50%. The process is suitably carried out in two stages: (i) a heating up stage in which more than the calculated quantity of hot inert gas is introduced and (ii) an aftercondensation stage in which less than the calculated quantity of cold inert gas is introduced. The inert gas may be recycled, that being used for the second stage being purified.

Patent ES-420828-A1 (ES)
Title: Method and apparatus for fabricating tubing
IPC: B21D43/05
Filed: 1973-11-24
Abstract: Tubing is cut to measured lengths which are fed to a series of aligned work stations where they are progressively operated upon by assembling end fittings, flaring the ends, and then bending the tubes to the required shape. Transfer between stations is accomplished by oscillating shafts disposed between the stations carrying transfer arms which swing back and forth above the work level. Each work station has a pair of tube clamps and each pair of arms carries grab clamps. Controls prevent release of the tube clamps at each station until the grab clamps have engaged the tube, and prevent release of the grab clamps until the tube clamps at the next station have engaged the tube. In this manner, lateral positioning of the tubes is controlled. The tubes are end-aligned before each flare station and the first bending station.
