Title: Alkoxylation Products
Inventor: MAURER WERNER
IPC: D06M13/372
Filed: 1968-08-29
Abstract: 1,184,860. Alkoxylation products. FARBENFABRIKEN BAYER A.G. 29 Aug., 1968 [29 Aug., 1967; 17 April, 1968], No. 41315/68. Heading C2C. The invention comprises novel alkoxylation products derived from 1-alkoxy-3-aminopropane-2-ols of the general formula in which R 1  is an alkyl or alkenyl radical or a cycloalkyl radical which may be substituted or an aralkyl radical which may be substituted by halogen or lower alkyl groups; R 2  is H, an alkyl or alkenyl radical or a cycloalkyl, aralkyl or aryl radical which may be substituted; R 3  is an alkyl radical or a cycloalkyl, aralkyl or aryl radical which may be substituted or the sulphonyl radical -SO 2 R where R is a C 4-18  alkyl radical or a cycloalkyl or aryl radical which may be substituted by halogen or lower alkyl groups and in which the total number of carbon atoms in R 1 , R 2  and R 3  amounts to 10-30 with an alkylene oxide. The alkylene oxide used may be ethylene oxide or propylene oxide and the alkoxylation is preferably performed at 120-160‹ C. in the presence of an alkali metal hydroxide catalyst. Amongst the examples the ethylene oxide adducts of the following compounds were prepared: 1-n-octyloxy - 3 - (2 - ethylhexyl) - amino - propanol - 2, 1 - cyclohexyloxy - 3 - di(2 - ethylhexyl) amino - propanol - 2, 1 - n - butoxy - 3 - pentadecyl - sulphonamido - propanol - 2 and 1 - noctyloxy - 3 - (4 - tolyl - sulphonamido) - propanol-2. 1 - n - Octyloxy - 3 - chloro - propanol - 2 is obtained by the reaction of n-octanol and epichlorohydrin. The 1-(2-ethylhexyloxy)-, 1-cyclohexyloxy -, 4 - tert - butylcydohexyloxy -, 1- butoxy and 1 - n - hexyloxy - 3 - chloro - propanol-2 were similarly obtained. 1 - n - Octyloxy - 2,3 - epoxy - propane was obtained from 1 - n - octyloxy - 3 - chloro - propanol-2 by treatment with NaOH. The 2,3- epoxy propanes having the above alkoxy or cycloalkoxy radicals were similarly obtained. The starting materials for the alkoxylation were obtained by treating the 2,3-epoxy-propanes with amines e.g. 2-ethylhexylamine, dibutylamine and pentadecyl sulphonamide.

Title: Process for making minute capsules
IPC: A61J3/07
Filed: 1962-11-01
Abstract: 952,030. Encapsulating processes. NATIONAL CASH REGISTER CO. Nov. 1, 1962 [Nov. 10, 1961], No. 41353/62. Heading B8C. Minute capsules consisting of solid or liquid water insoluble material contained within a wall of hardened hydrophilic polymeric material are formed by dispersing by agitation the core particles in an aqueous vehicle with one or more hydrophilic film forming polymeric materials, inducing coacervation to surround each core particle with a liquid wall and subsequently adding a reactant to harden the wall and render it water insoluble. Optionally the wall may afterwards be rendered less rigid by treating with a plasticizer. Coacervation may be induced by lowering the pH value or addition of a coacervating salt. As an example, droplets of trichlorotrifluoroethane are encapsulated as follows:- Introduce into a container 100 millilitres of 5% by weight aqueous solution of polyvinylimidazole and the same quantity of the same strength solution of gum arabic. Add 300 millilitres of water and adjust to a pH above 9.5 to inhibit the immediate formation of complex units. Add with agitation 25 millilitres of the liquid being encapsulated, the agitation being used to control the droplet size to, say 100, microns diameter, and adjust the pH value quickly to 6.9-7.0 to induce coacervation. Continue agitation and add a metallic chelating salt e.g. CrCl 3  or CuSO 4  to rigidify the walls. Five millilitres of CrCl 3  may be used. The capsules so formed may be plasticized by adding 40 millilitres of a 75% by weight aqueous solution of sorbitol to the vehicle.

Abstract: 1354760 Purifying hydrocarbons with adsorbents UNION CARBIDE CORP 7 Sept 1971 [8 Sept 1970] 41566/71 Heading C5E [Also in Division B1] An adsorption purification process comprises passing a first feed containing a strongly adsorbed impurity and a less strongly adsorbed major component (A) into a bed of zeolitic molecular sieve adsorbent to adsorb the impurity and a portion of the major component (A), without intervening desorption of the impurity from the bed, passing a second feed containing a strongly adsorbed impurity and a major component (B) which is less strongly adsorbed than the major component (A) through the bed in the co-current direction to adsorb impurity from this second feed and to desorb the previously adsorbed portion of the component (A), and thereafter desorbing at least a portion of the total adsorbed impurity from both streams. The temperature rise caused by passing the first feed through the bed can be reduced by adsorbing a portion of the component B onto the bed before passing the first feed through the bed. The desorption can be carried out with a hot purge gas. Coking of adsorbed hydrocarbons upon desorption can be avoided by first passing water vapour into the bed so that the adsorbed impurities are displaced by the water vapour which is then itself displaced by the hot purge gas. The adsorption can be carried out in the liquid or gaseous phase at -40 to 100 C. and 1 to 100 atmospheres. The first stream can mainly comprise a mixture of butanes and butenes containing water, methyl mercaptan and butadiene impurities and the second stream can mainly comprise a mixture of butanes containing water and methyl mercaptan; other feedstock systems which can be treated include: (1) a first stream of normally gaseous hydrocarbons of higher molecular weight than methane and containing hydrogen sulphide, mercaptans, ethylene and acetylene impurities and a second stream of natural gas containing hydrogen sulphide; (2) a first stream of ethylene and/or propylene containing carbon dioxide and a second stream of natural gas containing carbon dioxide; (3) a first stream of naphtha and a second stream of natural gas; and (4) a first stream of sour C 4  to C 9  natural gasoline and a second stream of isobutane containing sulphur compounds. The process can be used to dry cracked gas and natural gas.

Abstract: 1,065,887. Reducing refuse; impact pulverizers. P. DE GRAAFF. Oct. 25, 1963 [Oct. 31, 1962], No. 42241/63. Heading B2A. [Also in Division B8] Apparatus for reducing the size of refuse and conveying it to the interior of a hopper I of a refuse collector, comprises a system including a driven shaft 8, Fig. 1 having radial projections 9, which are in planes perpendicular to the shaft and may be helically arranged, the system being contained in the curved feed channel 4 in the loading compartment 2 of the collector, which also includes partitions 10 between the projections 9 and perpendicular to the shaft. The loading compartment 2, which has a feed opening 5, is curved in the portion of the lower wall 6 which defines the feed channel, the portion 7 sloping upwardly. In operation, refuse is fed via the opening 5 and is compressed and/or broken between the edge of the projections 9 and the partitions 10, and is gradually pushed into the hopper 1, a grid 12 stripping any refuse adhering to the projections. The shaft 8 is driven via chain wheels 15, 17 and a chain 14 from a hydraulic motor 22 and gear box 19. In a modification, scrapers (24, Fig. 3) having curved ends (25) are pivoted on an axle (26), their swinging movement during the passage of a projection exerting pressure on refuse in the transit channel, so that it is pushed on in the direction of the hopper. The scrapers may alternatively be spring-urged against the projections 9 or be made of a yielding, flexible material. Projections 9 may be provided on the shaft 8 for each of a number of feed openings and staggered by e.g. 120 degrees where there are three such openings, and scrapers (24, 27, Fig. 4) are arranged so that the leading compartment is sealed and the stripping grid 12 is then omitted. The stripping grid 12 may include scraping walls (30, Fig. 5) which embrace the projections (9) to scrape their sides, and the shaft (8) runs in sleeves (32) welded to the partitions and the grid 12, so that it is entirely protected.
