Title: Improvements in or relating to the determination of gas mixtures
Inventor: SIETH JOACHIM
IPC: G01N25/14
Filed: 1963-08-13
Abstract: 970,609. Gas analysis; electro physical measurement. SIEMENS SCHUCKERTWERKE A. G. Aug. 13, 1963, No. 31993/63. Headings G1B and G1N. A process for the quantitative continuous analysis of gas mixtures, wherein a gas mixture e.g. flue gases containing sulphur dioxide and trioxide is mixed with the vapour of an auxiliary medium whilst it is condensing e.g. water vapour, whereby one or more gas components, i.e. sulphur trioxide, are separated from the mixture and combined with the condensing vapour, so that the concentration of the components can be determined. The apparatus shown in the drawing is suitable for use in determining the sulphur trioxide content of gases, and also the sulphur dioxide content by absorption in water. The gas mixture is sucked through the apparatus by a diaphragm pump e. Salt-free water is supplied to a flask c1 through a flowmeter a2 and regulating valve 1. The water is boiled under reflux in the flask c 1 and is condensed by a condenser b 1. The gas mixture is drawn through a flowmeter a 1 into the condenser b1 where sulphur trioxide dissolves in the condensing water vapour to give sulphuric acid which falls into the flask c1. The gases then pass through a bulb condenser b2 to a second flask c2 containing the liquid from the flask c1 under reflux. The gases again mix with the condensing water vapour in a condenser b 3 to remove any remaining sulphur trioxide. The sulphuric acid solution from the flask c2 is fed to a throughflow conductivity cell f1 connected to a measuring instrument m1 recording on a recorder n1. The instrument may be calibrated to read directly the concentration of sulphur trioxide in the gas mixture. The remaining gases now pass through a control valve k to an adsorption cell g to which salt-free water is supplied through a flowmeter a4, the gas being dispersed by a glass frit. Sulphur dioxide in the gas is adsorbed to give sulphurous acid, and any remaining traces of sulphur dioxide are adsorbed as the gas and water pass through an adsorption coil h which is thermostatically controlled. The gas is separated in a vessel i, and the sulphurous acid solution is fed to a second throughflow conductivity cell f2 from which the sulphur dioxide concentration in the gas may be obtained.

Title: Improvements in and relating to the production of esters from solid acids or anhydrides
IPC: C07C69/80
Filed: 1949-12-16
Abstract: Esters are made from alcohols (or mixtures of alcohols) and slight excess of solid organic acids or anhydrides using sulphuric or other strong acid as catalyst and preferably toluene or other entrainer for the water produced; the process is characterized by: (1) the reactants are stirred mechanically the whole time and are heated in a way ensuring uniform temperature, e.g. by indirect heat exchange with a liquid medium such as an oil bath, water bath or liquid-traversed coil; (2) the acid or anhydride is added to the alcohol or alcohol+entrainer and completely dissolved before the catalyst is added; and (3) the temperature is kept appreciably below the point at which sensible esterification occurs until all the acid or anhydride is in solution.  This technique minimizes discoloration of the ester. Figures are given of the depth of colour produced from mixed C6-C9 alcohols with phthalic anhydride, sulphuric acid and toluene (a) heated by the method of the invention and (b) mixed and at once heated up to reflux.  Further improvement is achieved by preliminary purification of the alcohols.  The process is also applicable to the preparation of di-nonyl glutarate, di-nonyl sebacate, di-butyl phthalate, nonyl butyl phthalate and nonyl isopropyl phthalate, and to glutarates, adipates, sebacates and phthalates generally.
