Title: Process for preparing branched chain primary sulfate esters
IPC: C07C303/24
Filed: 1951-01-18
Abstract: Branched chain primary alkyl sulphates are obtained by reacting ethylene with a tertiary olefin in the presence of 80-100 weight per cent sulphuric acid at a temperature of -25 DEG  C. to +80 DEG  C. and at an ethylene partial pressure of 50-1000 p.s.i.g.  The tertiary olefin may be aliphatic or alicyclic and may range from C4 to C30 or higher.  The molar ratio of ethylene to tertiary olefine should preferably be greater than 50 : 1 but lower ratios may be employed when a tertiary olefine such as tetraisobutylene where the rate of self polymerization is negligible is employed. The reaction is preferably effected by adding the tertiary olefin to thn reactor containing the sulphuric acid and ethylene under the desired pressure and an inert hydrocarbon diluent is preferably employed.  The diluent may be a saturated aliphatic or alicyclic hydrocarbon preferably a normal or iso-paraffin and when a branched chain hydrocarbon is employed as diluent it should preferably have the same carbon skeleton structure as the tertiary olefine.  In a continuous type operation the tertiary olefine may be fed at the bottom of a reactor containing the sulphuric acid intermixed with the inert diluent and continuously withdrawing the tertiary olefine-free diluent from the top of the reactor.  The primary sulphates produced by the process may be hydrolysed with water to give branched chain primary alcohols. Examples are given in which (1) isobutylene is reacted with ethylene using 95.5 weight per cent sulphuric acid at -15 DEG  C. using n-heptane as p  diluent to yield a primary sulphate ester which on hydrolysis with water yields 3,3-dimethyl-butanol-1; (2) a mixture of 2-methyl pentene-2 and 2-methylpentene-1 is similarly reacted with ethylene to give 3,3-dimethyl-hexanol-1; (3) a mixture of hexenes in which the ratio of tertiary/secondary olefins is about 3.5 : 1 yields hexyl ethanols, and (4) 1-methylcyclopentene yields a 2-alkylated ethanol in which the branching is an alicyclic radical.  A Table is also given in which the production of various alkylated ethanols from the corresponding tertiary olefine and ethylene using 95-96 per cent sulphuric acid is described.  The primary sulphate esters may be reacted with hydrogen halides such as HI, HBr2, HCl, HF to yield the corresponding halide, the reaction being effected by treating the primary sulphate ester with anhydrous hydrogen halide at 0 DEG  to 100 DEG  C. and preferably at 25 DEG  to 50 DEG  C.  The primary sulphate esters also react with ammonia to form primary amines and on alcoholysis form other esters and mixed neutral sulphates whilst on heating the acid sulphate esters decompose to form alpha olefines. It is stated that the acetate derived from 3,3-dimethylbutanol and glacial acetic acid is useful as a lacquer solvent and that the di-octyl phthalate ester derived from phthalic anhydride and the branched chain alcohol of the invention can be employed as a plasticizer for polyvinyl chloride-type plastics.

Title: Motorised pump with associated heat exchanger, for pumping slurries
IPC: F04D13/06
Filed: 1966-01-14
Abstract: 1,129,321. Heat exchangers. PALL CORP. 14 Jan., 1966 [21 Jan., 1965], No. 1930/66. Heading F4S. [Also in Divisions B1 and H2] A wall 64, the whole or part only of the surface of which is porous, separates and conducts heat between two fluid streams (circuits A and B) in a heat exchanger. The porous portion of the wall permits the passage of fluid through the wall thereby limiting the pressure differential between the fluids. Where one of the fluids is a suspension or slurry the porous wall portion acts as a filter, preventing the passage of entrained solids from one fluid stream to the other. The wall may comprise a tube or a plate and the respective fluids may flow in cocurrent, countercurrent or cross flow relation. The wall may be made of a sintered, fibrous or woven, metallic or non-metallic, natural or synthetic material or it may be a solid plate having small holes punched therein. Heat transfer, when materials of low heat conductivity are used, may be augmented by the addition of metal plates or fins to the wall. In the apparatus shown, a slurry or suspension is pumped by a rotary impeller 21 from an inlet 20 to an outlet 19 of a pumping chamber 22. The impeller is driven by an electric motor adapted to permit the rotor to be cooled and lubricated by a liquid circulated in a circuit A by an impeller 43. The circuit A includes channels 45, 53 in the rotor bearings, conduits 75 and 78, and the fluid space 66 in the heat exchanger. The coolant flowing in circuit A is cooled in the heat exchanger by a slurry stream tapped from the pump chamber 22 and flowing in a circuit B. A conduit 80 of circuit B is connected to a relatively high pressure zone of the impeller chamber 22 thereby inducing a flow through the circuit B which comprises conduits 80, 81 and an annular fluid passage 65 in the heat exchanger. The motor and pump casing is made up of a number of separately made parts which may be bolted together (as shown) or bonded. The pump and motor may be in separate housings and the heat exchanger may be combined with the pump and/or motor housing.

The Fig. shows an amplifier for feeding the deflection coils of a display system in which two or more different signals are simultaneously displayed by switching (at 42), the input between signal sources such as 40, 41. The circuit comprises a basic class B linear amplifier 2, 3, 4, 5 having input diodes 15, 16 for steering the different polarities of signals to the two halves of the amplifier. Negative feedback is provided from resistor 38 and if a sudden jump in signal level occurs on switching between the signals the current rise would be relatively slow. The initial feedback voltage would thus be low and a large net signal appears at the input. This overcomes the threshold of a switching circuit 25, 24, 17 or 28, 27, 18 connecting are larger voltage source + U 2  or -U 2  to the coils to produce a rapid change of deflection current to the new value. Diodes 19 and 20 are for decoupling and 22, 23 for protection.
