Title: Improvements in the production of organic acid esters of cellulose
Inventor: BATES HAROLD
IPC: C08B3/22
Filed: 1952-06-09
Abstract: Cellulose is esterified with an organic acid anhydride in the presence of more than 350 per cent (on the weight of the cellulose) of methylene or ethylene chloride as solvent and sulphuric acid as catalyst, and the cellulose ester so produced is ripened by adding water to the primary esterification solution in amount sufficient both to hydrolyse residual acid anhydride and to provide water for the ripening reaction, neutralizing substantially all the sulphuric acid in the solution, removing by distillation a substantial proportion of the methylene or ethylene chloride (without reducing the methylene chloride content below 30 per cent or the ethylene chloride content below 50 per cent, on the weight of the cellulose), and then heating the solution to 100-190 DEG  C. and maintaining it between these temperature limits until the desired degree of ripening has taken place.  Preferably the amount of solvent distilled off is such as to leave in the solution between 30 and 150 per cent of methylene chloride or between 50 and 200 per cent of ethylene chloride.  The process is applicable to the production of cellulose acetate, propionate, butyrate, and other organic acid esters of cellulose.  The cellulose may be purified cotton linters, wood-pulp, pulp from straw or grasses, or a mixture of cotton linters and wood-pulp cellulose.  During the process, so much of the solvent may be distilled off that the solution remaining has the form of a stiff plastic mass.  The sulphuric acid may be neutralized by means of a carbonate, acetate, oxide or hydroxide of an alkaline-earth metal, zinc, or aluminium.  If desired, the ripened solution may be thinned by the addition of acetic acid or acetone before the cellulose ester is precipitated.  Specification 620,726 is referred to.

Filed: 1958-05-09
Abstract: 853,326. Electric tests. DEUTSCHE GOLDUND SILBER-SCHEIDEANSTALT VORM. ROESSLER. May 9, 1958 [May 25, 1957]. No. 14971/58. Class 37 In a process for potentiometrically measuring and reducing chromate ions in an aqueous solution in which the measurement is carried out with the aid of a glass electrode and a platinum measuring electrode, passivation of the latter is avoided by adding to the solution a reducing agent, e.g. sodium bisulphite or sulphurous acid, in an amount so controlled by the potential measurement that the solution has alternately an oxidising action and a reducing action. As described, a sample of the test solution flows through the measuring electrode in a branch pipe from a measuring and detoxicating vessel, the resulting measurement controlling a valve through a regulator to supply reducing agent to the solution at the inlet to the vessel. From the vessel the solution passes to a final reaction container where the reducing process is completed. Prior to measurement, the pH value of the sample is made less than 2 by the addition of sulphuric acid, and the sample is also heated to a temperature above 15‹C., preferably above 30 ‹C., to prevent time lag in the measurement process.

Abstract: 1,209,736. Treating sewage. DEUTSCHE GERATEBAU G.m.b.H. & CO. K.G. 21 March, 1969 [22 March, 1968], No. 15037/69. Heading C1C. [Also in Division B1] Apparatus for sewage treatment by the activated sludge process comprises a tank 1 with an upper chamber 3 and a lower chamber 2, a surface aerating and circulating rotor 17 in the chamber 3 and a second rotor 18 on the same shaft below the chamber floor 4, and an air pipe 26 discharging in the working zone of the rotor 18. A supply passage 9 and a riser passage 11 extending into the lower chamber are defined by walls 6 and a partition 8. Sewage enters at 10, descends passage 9 and is guided by a deflector plate 16 attached to the underside of floor 4 into the upper part of the lower chamber where it is turbulently mixed with air from the pipe 26 subdivided by the rotor 18. Leaving the lower chamber the sewage passes up riser passage 11 and through inlet 12 into chamber 3, and after further aeration therein out under wall 5 into the clarifying chamber 7, where it overflows into a launder 13 and is discharged at 14. The inlet 12 has a tongue 20 providing an ejector action to remove scum from the surface of the riser passage 11. A return flow opening 21 with a vertically and horizontally adjustable shutter 22 allows a controlled amount of excess sewage and activated sludge to pass by wave motion from chamber 3 to passage 11 where the sludge sinks by gravity against the rising current inro the upper region of chamber 2, and thence, after retention for a time by the agitation due to rotor 18, to the bottom of the tank. An aperture 28 in the deflector plate 16 allows air to escape into passage 9 from the air cushion which forms in chamber 2 under flow 4, and a baffle 33 restricts turbulence to the upper region of chamber 2. Eejctor tubes 34 return sludge from the clarifying chamber to chamber 3.

Patent GB-584371-A (GB)
Title: Improvements in or relating to the production of para-alkyl phenols
IPC: C07C37/14
Filed: 1943-09-16
Abstract: The process of preparing a para-alkyl phenol by reacting the phenol with an olefine in the presence of an acid or with an acid extract of an olefin until the phenol is partly alkylated, followed by neutralization, fractionation, and digestion with an isomerisation catalyst such as aluminium chloride is modified in that a rearranging catalyst comprising activated clay and a free acid condensation catalyst is used in the digesting step.  The intermediate condensation product may be prepared either by mixing the phenol and olefine and treating the mixture with an acid catalyst, or by absorbing the olefines in sulphuric acid and allowing the resultant product to react with the phenol.  The amount of activated clay which is used may vary between 0.5 per cent and 10 per cent of the weight of the reaction mixture.  Clays mentioned as suitable for the present invention include Tonsil or that known under the Registered Trade Mark "Retrol."  The reaction is carried out at temperatures between 100 DEG -160 DEG  C. preferably at about 140 DEG  C.  The olefins used may be either straight or branched chain olefins or cyclic olefins.  In examples: (1) phenol and a mixture of amylenes containing 50 per cent branched chain amylenes was treated with concentrated sulphuric acid, the reaction temperature being kept low. The product was fractionated and material boiling below 90 DEG  C. removed.  The residue was treated with activated earth known under the Registered Trade Mark "Retrol," at 145 DEG  C., filtered and fractionated to give o-tertiary amyl phenol, and di-tertiary amyl phenol; (2) a mixture of o-cresol and mixed amylenes is treated as in example (1) with concentrated sulphuric acid and worked up as before to give p-tertiary-amyl-ortho cresol; (3) concentrated sulphuric acid is added to a mixture of cyclohexene and phenol in pentane.  The reaction mixture is stirred and heated under reflux, fractionated and the high boiling residue treated with the acid activated clay known as Super-Filtrol followed by working up as before to give p-cyclohexylphenol; (4) a mixture of phenol with mixed normal and iso-butanes is treated as in example (3) except that the activated clay used is that known as Attapulgus contact clay; (5) mixed amylenes are treated with sulphuric acid and the resulting mixture of tertiary hydrogen amyl sulphate and tertiary amyl sulphate reacted with phenol and the intermediate isomerization product treated with "Retrol" clay and worked up as before to form tertiary amyl phenol. Specification 420,636 is referred to.
