Title: Dialkyl phosphoryl monochlorides and process for making the same
IPC: C07F9/14
Filed: 1951-11-05
Abstract: The invention comprises as new compounds phosphoryl monochlorides having the general formula <FORM:0715336/IV (b)/1> wherein R1 is a substituted or unsubstituted alkyl group terminating in a CH2 group and preferably containing from 1 to 18 carbon atoms and R2 and R3 represent substituted or unsubstituted alkyl groups and preferably alkyl groups which together contain not more than 17 carbon atoms. The compounds may be prepared by reacting phosphorus oxychloride and a primary alkanol, preferably at temperatures below 25 DEG  C. to form the monoalkyl phosphoryl dichloride and then reacting the latter with a secondary alkanol preferably at temperatures between - 10 DEG C. p  and 50 DEG  C. and especially at from 0 DEG  C. to 25 DEG  C. The primary and secondary alcohols may be substituted by one or more unreactive substituents.  Other methods may also be used to prepare the monoalkyl phosphorus dichlorides.  The products may be converted to the orthophosphate esters which are stated to be useful as plasticizers, functional fluids, or paint removers.  They may also be reacted with amines to give compounds useful as corrosion inhibitors or hydrolysed with water to form compounds useful as textile treating compounds.  Examples describe the preparation of (1) n-butyl sec.-tetradecyl phosphoryl monochloride by adding butanol dropwise to phosphorus oxychloride to form n-butyl phosphoryl dichloride and then reacting the latter with the secondary tetradecanol viz. 7-ethyl-2-methyl-4-undecanol which is added dropwise to the phosphoryl dichloride; (2) to (6) 2-ethylhexyl sec.-butyl phosphoryl monochloride, 2-ethylhexyl capryl phosphoryl monochloride, methyl capryl phosphoryl monochloride, n-hexadecyl isopropyl phosphoryl monochloride, and n-hexadecyl sec.-tetradecyl phosphoryl monochloride respectively using the procedure as in (1) with the corresponding primary and secondary alcohols.  The secondary tetradecanol used in (6) is 7-ethyl-2-methyl-4 undecanol.

Title: Improvements in or relating to the manufacture of crystalline magnesium hydroxide
IPC: C01F5/22
Filed: 1936-09-24
Abstract: A process for the manufacture of crystalline magnesium hydroxide comprises calcining dolomite or dolomitic limestone at not less than 1200 DEG  C., forming a slurry of the oxides so formed and bringing the slurry into contact with an aqueous solution of a convertible magnesium salt such as sea water or salt brines, without the application of heat but with a velocity of flow just sufficient to bring about adequate mixing.  The slaking of the calcined dolomite may be effected by either cold fresh water, cold spent brine, or by steam, preferably in a trough-shaped vessel provided with paddles. The slurry formed from the calcined dolomite should have as high a concentration of solids as is compatible with the fluid form. Calcium bicarbonate may be removed from the sea water by the addition of a little dolomite slurry, followed by filtration.  The formation of crystalline magnesium hydroxide is promoted by including seed crystals in the brine, also by leaving up to 10 per cent of the brine unconverted, and by using spent brine for making the slaked slurry. The slurry of magnesium hydroxide is concentrated and may be either directly introduced into a rotary kiln and calcined, or maintained at about 90 DEG  C., for a time and filtered while hot.  The latter product may be converted to basic carbonate by treatment with furnace gases. The process may be carried out by introducing the slurry in a downward direction into a tank in which the brine through entering tangentially has a gentle rotary motion.  The precipitated magnesium hydroxide leaves the bottom of the tank by a pipe which passes through the bottom of a settling tank, terminating just below the surface of the liquid.  A modification of the settling tank has a conical vessel with vertex downwards, surrounding the pipe which has means for directing the flow to the apex of the cone.  The cone may have arms fixed to its outer surface which when given a rotary motion sweep the settled hydroxide towards the outlet sump, towards which the floor of the settling tank may slope.  Alternatively the brine may be introduced upwards through the vertex of a conical vessel, the fluid escaping by overflowing at the top into a surrounding settling vessel.  The dolomite slurry is introduced in a downward direction into the conical reaction vessel and falls to a level where the velocity of flow of the brine overcomes the cohesion of the slurry. Magnesium hydroxide is formed and being lighter is carried away with the spent brine.  Specification 433,253 is referred to.

Title: Dry-feed chlorinator and the like
IPC: B01F15/06
Filed: 1956-08-24
Abstract: 849,627. Mixing fluids in flow. FISCHER & PORTER CO. Aug. 24, 1956 [Dec. 2, 1955], No. 25993/56. Class 86 [Also in Groups XXVIII and XXIX] A dry feed system for introducing a minor fluid into a major moving stream comprises an ejector 110, Fig. 5 (see Group XXVIII) through which flows the major stream of water from a supply line 28, which flow induces the flow on the minor fluid of chlorine from the pipe 25, the resultant mixture being discharged to the outlet pipe 30. The chlorine is supplied from containers 99, 100 through a filter 18 and pipe 21 to the inlet 22 of a regulator 23, the outlet 24 of which is connected to the pipe 25. The regulator 23, Fig. 6, is provided with a gas inlet chamber 75 separated from a chamber 70, vented to atmosphere, by a diaphragm 39 and a gas outlet chamber 98 separated from a balancing chamber 81 by a diaphragm 40. The inlet chamber 70 is connected to balancing chamber 81 by piping connecting an outlet 31 to an inlet 32 and thence by passages 63, 64 and the inlet chamber 70 is also connected to the outlet chamber 98 by piping from the outlet 31 to an inlet 34, which piping contains a rate valve in the form of an adjustable orifice. Such piping is shown in Fig. 5 with the rate valve 35 and a flowmeter 33 which is the subject of Specification 849,628 (see Group XXIX). A spring loaded gas inlet 56 is provided with a stem 58 and abuts a plug 45 attached to the diaphragm 39. The diaphragm 40 is loaded by a spring 94 and carries a plug 86 housing a valve member 88 which throttles the outlet 24. When the suction is created by the stream of water the diaphragm 39 moves down to open the valve 56 and admit the gas to the regulator. The gas passes from the inlet chamber 75 to the balancing chamber 81 and also through the rate-valve to the outlet chamber 98. Depending on the setting of the rate-valve the pressure differential on either side of the diaphragm 40 and the spring 94 causes this diaphragm to assume a certain position which thus determines the throttle setting of the outlet 24 and the amount of gas drawn into the stream. A vacuum-relief valve 49 is provided having a stem 48 and end member 50 which is opened by a member 46 screwed to the plug 45 when a sudden rise in the vacuum in the system occurs, this allows atmospheric air to enter the system through the vent chamber and passage 80. Should the pressure in the gas inlet chamber suddenly increase the diaphragm 39 rises to open a pressure relief valve 66 to allow the gas to escape to the atmosphere.

Title: Process for the preparation of ª†-4-chloro-2-methylphenoxybutyric acid and derivatives thereof
Inventor: HEYWOOD BASIL JASON
IPC: C07C59/68
Filed: 1954-09-09
Abstract: Gamma - 4 - chloro - 2 - methyl - phenoxybutyric acid is made by heating an alkali metal salt of 4-chloro-2-methyl-phenol with butyrolactone under substantially anhydrous conditions.  The reaction is suitably carried out by treating the corresponding phenol with aqueous alkali, removing the water by co-distillation with an entrainer liquid, which may form an azeotropic mixture with water, adding butyrolactone to the resulting mixture of alkali metal phenoxide and entraining liquid, removing the entrainer by distillation and heating the residue at a temperature above 140 DEG C., preferably at 140-210 DEG  C. to complete the reaction.  The reaction may also be carried out by heating a mixture of the phenol in aqueous alkali with butyrolactone and the entrainer so that the azeotrope and the entrainer are successively distilled off, whereafter the temperature is raised to that required for reaction between the phenoxide and the butyrolactone. Suitable entraining liquids include chlorobenzene, white spirit, o-dichlorobenzene and xylene, the preferred liquids being alcohols boiling in the range 100-200 DEG  C. such as n-butanol.  The reaction between the alkali-metal phenoxide and the butyrolactone may also be carried out continuously by passing the reactants, optionally under pressure, through a heated tube.  The free acid may be isolated from the alkali metal salt obtained as reaction product, by known methods.  The products are used as selective herbicides.  Specification 758,980 is referred to.

Glass, particularly in the form of sheets or of hollow bodies, is rapidly cooled in a chamber of which the cooled walls are selectively absorbent and return to the glass a radiation of which the intensity is less than that of the radiation received and has a composition different from that of the radiation received. In the form shown the cooling chamber has water-cooled walls 1.which, on the sides 4 facing the glass F, are of high reflecting power for infra-red rays, and superimposed on this surface, nearer the glass, is a layer 5 of small thickness having a selectively absorbent effect on the infra-red rays received, e.g. it absorbs those of a wavelength above 3 microns. The reflecting surface may be anodically oxidized polished aluminium; the absorbent layer may be a varnish in which powdered glass, containing infra-red-absorbing constituents, e.g. oxides of iron, cobalt, nickel or copper, is incorporated. The effect of this cooling is to create in the temperature zone including the critical annealing zone a slight temperature gradient throughout the glass which is less than that obtained by cooling the glass by radiation on to the walls of a totally absorbing black chamber surrounding the glass. Specification 724,326 is referred to.
