Title: Process for the manufacture of the lower alkyl esters of unsaturated aliphatic acids
IPC: C07C69/54
Filed: 1958-11-03
Abstract: An unsaturated aliphatic ester is obtained by contacting a vapour-phase mixture comprising an a ,b -unsaturated aliphatic carboxylic acid and at least the stoichiometric proportion of a saturated aliphatic alcohol having not more than 8 carbon atoms with silica gel at a temperature above the boiling-point of the reactants and products in the presence of added water said water being added in a proportion of at least 1 mol. per mol. of said acid.  The molar ratio of added water to acid is preferably in the range of 1 : 1 to 8 : 1 and it is preferred to use a stoichiometric excess of the alcohol.  Specified alcohols are methanol, ethanol, butanol-1 and 2-ethyl hexanol and specified acids are acrylic and methacrylic acids.  Suitable reaction temperatures are from 350 DEG  to 750 DEG F. at atmospheric pressure and the process is suitably conducted in a vertical vessel containing a fixed catalyst bed, the reactants being introduced at the bottom of the vessel and the product removed overhead, or vice versa. Preferred contact times are between 15 and 120 seconds.  Examples are given for the production of ethyl acrylate, n-butyl acrylate and methyl methacrylate and a comparative example is also given for the production of ethyl acrylate by reacting ethanol and acrylic acid in the vapour phase at 500 DEG  F. in the presence of silica gel but without adding water to the reaction.

Title: Improvements in or relating to radiation pyrometers
IPC: G01J5/12
Filed: 1953-12-18
Abstract: 748,317. Measuring heat radiation. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Dec. 18, 1953 [Dec. 23, 1952], No. 35294/53. Class 40 (3). In a radiation pyrometer on one junction of which is incident radiation from a source the temperature of which is to be measured, the effect of ambient temperature is compensated by a voltage which varies with ambient temperature and is proportionately reduced as the temperature to be measured increases. A known type of pyrometer is shown in Fig. 1 in which radiation is received on a target 3 situated in an evacuated glass envelope 1. The plate is in contact with thermocouple wires 4 which pass through a mica ring 2 and make connection halfway down lead-in wires 5, 51. The Specification states that the temperature of the target plate rises with ambient temperature but that the rate of rise is less if the source temperature is higher.. Accordingly the output signal of the thermocouple must be compensated by the introduction of a signal increasing with ambient temperature but reduced to an extent dependent on source temperature. An embodiment of the invention by which this is achieved is shown in Fig. 5. A thermocouple 7 measuring ambient temperature is in contact with the glass wall of the pyrometer. This thermocouple feeds a series arrangement comprising variable resistors 15, 16 and potentiometer 14. The output of the temperature measuring thermocycle 4 is added to a proportion of that produced by thermocouple 7 across potentiometer 14 and balanced against a voltage lifted from potentiometer 13 fed from battery 17. The sliders of potentiometers 13 and 14 are mechanically coupled and the potential difference between them is amplified at 10 and used to drive a servomotor which brings the difference voltage to zero. During the balancing of the output voltage of thermocouple 4 by the adjustment of potentiomotor 13 the proportion of the voltage produced by thermocycle 7 is adjusted in inverse sense. The position of the sliders at balance is then a measure of source temperature.
