Title: Production of trialkyl phosphites
IPC: C07F9/142
Filed: 1957-05-28
Abstract: A trialkyl phosphite is obtained by treating an alkanol with a phosphorus trihalide (a) in the presence of ammonium carbamate or (b) in the presence of another acid acceptor followed by purification of the reaction product in the presence of ammonium carbamate, in either case the ammonium carbamate being present in an amount which will maintain a pH of at least 7.  In one embodiment a trialkyl phosphite is obtained by reacting a phosphorus trihalide and at least a stoichiometric equivalent of an alkanol under anhydrous conditions in the presence of ammonium carbamate at a pH of at least 7.  A stoichiometric excess of ammonium carbamate may be used and in this event all or part of the ammonium carbamate may be added initially to the reactor and any remainder added as the reaction proceeds or an amount less than the stoichiometric amount may be added initially and the remainder formed in situ by adding anhydrous ammonia as the reaction proceeds thus forming additional ammonium carbamate by reaction with the carbon dioxide evolved.  The alkanol employed may be diluted with an inert organic solvent and the phosphorus halide may also be added in solution.  The temperature is preferably maintained at between -40 and +30 DEG C.  After the reaction is complete the solid materials present may be removed by filtration but it is preferred to add at least sufficient water to dissolve the solid materials and to agitate the resulting mixture. In another embodiment a trialkyl phosphite is obtained by reacting a phosphorus trihalide and at least a stoichiometric equivalent of an alcohol, adding anhydrous ammonia as acid acceptor to maintain the reaction mixture substantially neutral and washing the resulting reaction mixture with an aqueous solution containing sufficient ammonium carbamate to maintain a pH of at least 7.  An organic solvent may also be present in this case and sufficient water should be present to dissolve the water-soluble by-products.  Examples are given for the production of trimethyl, triethyl, triisopropyl and tri-n-heptyl phosphites from phosphorus trichloride and the corresponding alcohol, dichloromethane being used as solvent in each case.  Other alcohols specified are n-hexanol, 2-ethylhexanol, decanol and dodecanol and in the case of alkanols having 6 to 12 carbon atoms it is an advantage to use a small amount of a trialkylamine in the reaction mixture. U.S.A. Specification 2,678,940 is referred to.

Title: Improvements in or relating to electric tumbler switches
IPC: H01H23/16
Filed: 1926-07-08
Abstract: 274,271. Gladdy, T. July 8, 1926. Switches, quick-action.-In tumbler switches in which the quick make and break actions are governed by a compression spring in a toggle link or like connection between the dolly and contact arm, the intermediate joint of the toggle link motion is caused to traverse a straight or substantially straight path, thereby to ease the compression of the spring as the toggle passes over the dead-centre. One link of the toggle is formed by an extension of the dolly beyond its pivot f, the extension being bifurcated at h and each bifurcation being itself bifurcated. The bifurcations h embrace a bar a passing through lugs c in which it is secured by screwing or by a headed connection to one, and a rivetted connected to the other, lug. The bifurcations h also embrace an enlargement g of an intermediate joint pin i, the ends of which are slidable in the slots formed in the bifurcations h. The enlargement g, which may be of cylindrical, square, or hexagonal crosssection is apertured to receive the bar a along which it slides in a straight path. The other link of the toggle is formed as a U-shaped member l, the arms k of which are close slotted to receive the pivots of the pin i, and around each of the four pillars so formed is a compression spring n bearing against the bases of the slots and against plates p fitting over the arms k, the plates being thus urged against the pivots of the pin i. The member l is slotted at its lower end to rest pivotally on a pin r secured between the arms s of the stirrup t of the contact arm carrying the contact y. The arms s are mounted on pivot screws u and lugs v and have ears x which are engaged by the arms k for positive actuation if the springs fail. The lugs 1 for pivotting the dolly and the lugs c, v are provided on a plate z under the bridge b, the plate being secured by the bridge fixing screws which pass up through the china base into apertures 2, formed by bending down the lugs v, and into tapped holes 5 in the feet w of the bridge. The Provisional Specification also describes a form in which the inner link of the toggle is a bar surrounded by a compression spring acting between the outer pin of the toggle, in a hole in which the end of the bar slides, and the bar a, the bar forming the link being a right angle projection on the intermediate pin which is pressed by the spring so as to abut slidably on the inner face of the bar a. The outer joint pin works in slots in the side arms of the contact arm.
