Title: Process for attack of bauxite with alkaline solution
IPC: C01F7/062
Filed: 1968-03-18
Abstract: Bauxite is subjected to the action of an aqueous solution of caustic soda and sodium aluminate (to achieve a dissolution of the alumina content of the bauxite) in a series of pressure stages of increasing temperature. Any intermediate (or final) stage 211 receives the reaction suspension from the preceding stage 21 and is heated by a corresponding member of a series of exchanger expansion stages 24, 241, these expansion stages being supplied in series with the hot aluminate/"red muds" suspension from the final pressure stage. Water vapour from each expansion stage 24, 241 heats the suspension in each pressure stage to close to its boiling point by direct injection in a mixing re-heater 22, 221. The re-heated suspension remains in a reservoir for less than 1 hour while the solubility equilibrium for the temperature is reached. Circulation means pass into the following stage the contents of one stage increased by the condensed steam. The suspension leaving the final stage is heated by live steam and then passed back along the series of expansion stages. Part of the vapour produced in each expansion stage is used to heat the next expansion stage while the remainder is passed to the appropriate mixing reheater.
Patent ES-359534-A1 (ES)
Title: Production of cis-1,2-propenylphosphonic acid
IPC: C07F9/143
Filed: 1968-10-25
Abstract: cis-1,2-Propenylphosphonic acid (I) is obtained by reacting phosphorus trichloride with at least two equivalents of a C 1 -C 5 alkyl, or C 2 -C 5 alkenyl alcohol or an alkalkyl alcohol, or a phenol, or with at least one equivalent of a dihydric phenol, e.g. catechol or of a C 2 -C 5 alkylene glycol in an inert organic solvent, reacting the resulting diorgano phosphorochloridite (II) with propargyl alcohol to form a 2- propynyl di-organo-phosphite (III), rearranging the latter to form the corresponding allenyl phosphonic acid diester (IV), hydrogenating the latter to form the cis-1,2-propenyl phosphonic acid diester (V) and cleaving the latter to form the free cis-1,2-propenyl phosphonic acid (I), the process being generally carried out without isolating the intermediate compounds. The 2-propynyl diorganophosphite (III) gradually rearranges on standing to form (IV) but the rearrangement is preferably effected by heating the mixture at 50-100 C. or to reflux, the heating being preferably carried out in an inert atmosphere, e.g. of N 2 or helium. The diester (IV) is then hydrogenated, preferably catalytically, in order to form the diester (V). Suitable hydrogenation catalysts are Pd/C, Pd/CaCO 3 and Raney nickel. The free olefinic acid (I) may be obtained from the cis-olefinic diester (V) by acid or base-acid hydrolysis or where appropriate by pyrolysis in the absence of a solvent. Where, however, the ester group in (IV) is aralkyl or substituted aralkyl, e.g. benzyl or chlorobenzyl, the hydrogenation step additionally serves to remove the ester groups thus yielding (I) directly. When acid is used in the ester cleavage of (V) to (I) the acid may be (I) itself or may be a strong mineral acid or an organic acid, e.g. benzene sulphonic acid or p-toluene sulphonic acid. Acidic ion exchange resins and catalytically acidic surfaces, e.g. sea sand, silica gel or acid washed alumina may also be used. When pyrolysis is used to cleave the ester it is suitably effected at 85-200 C. in the presence or absence of an acid catalyst. The reaction in the first two steps may be carried out in the presence of an acid-binding agent, e.g. a tertiary amine, or an oxide such as propylene oxide. In a modification of the process the allenylphosphonic acid diester (IV) is rearranged to form an [alpha],#-propynylphosphonic acid diester and the latter hydrogenated to produce the cisolefinic diester (V) which is then cleaved. The cis-propenyl phosphonic acid product may be converted to the antimicrobial agent ( ) (cis- 1,2-epoxypropyl)-phosphonic acid by oxidation with H 2 O 2 either directly or by first converting to the monobenzylamine salt prior to the oxidation. The invention also includes per se the compound di-t-butylallenyl phosphonate obtained as an intermediate in the third step of the process using the appropriate reactants.

Patent ES-369656-A1 (ES)
Title: Method for production of solid state storage panels
IPC: H04N3/14
Filed: 1969-07-17
Abstract: In a process of making an electroluminescent storage device which may be included as a target in an evacuated storage tube as in Fig. 9 of Specification 1,201,374, portions of a transparent conductive layer on a transparent substrate are converted into an opaque state whereby the portions prevent subsequently deposited light-sensitive layers overlying the portions from being exposed to actinic radiation through the substrate. An electroluminescent device is made by providing a layer of photoresist (14) on a layer of SnO (12) on a glass substrate 10. The photo-resist is exposed through a mask (18, Fig. 1, not shown) and the unexposed portions removed. The exposed portions of SnO are reduced to tin (24) electrolytically and the portions of tin and photo-resist (24, 20) are coated with a layer of photo-resist and electroluminescent material (26, Fig. 3, not shown). The device is exposed to light through the substrate 10 and the tin portions (24) and unexposed portions of the photoresist-electroluminescent layer removed to leave photoresist-electroluminescent portions 32 on photoresist and tin-oxide portions 22, 20. The gaps between portions are filled and covered with epoxy resin 33 as electrical and moisture insulation and the upper surface with a field effect semi-conductor control layer 34. The control layer may comprise ZnO, CdO or PbO or a layer of CdS, ZnS, CdSe or ZnO with an insulating layer on it, if charge retention properties are inadequate. Alternatively a barrier layer may be made by suitable doping to provide a PN junction. In operation, a charge pattern is established on surface 34 and this governs the resistivity between adjacent portions and hence the light emitted by the electroluminescent portions 32. The charge pattern may be established by full-frame or line-by-line imagewise exposure of the charged surface with one or more scanning light point sources in the case of a layer of ZnO or other photoconductor, by corona discharge through a shaped mask, by corona discharge of an X-Y matrix or pin matrix in an imagewise fashion or by a scanning corona discharge and negative ion deposition is instanced. The tin oxide layer may be replaced by Cu 2 I 2 , In 2 O 3 , AgI, CuS or antimony chloride. Reference is made to Specification 1,235,310.
