Title: Aldol condensation of acrolein dimer
IPC: C07D309/26
Filed: 1955-05-19
Abstract: 2,3 - Dihydropyran - 2 - yl - 2 - formyl - 2,3 - dihydropyran-2-yl-carbinol is made by adlol condensation of 2,3 - dihydro - 2 - formyl - 1,4 - pyran (acrolein dimer) at elevated temperature under substantially anhydrous conditions in the presence of a cupric salt of an organic acid, such as cupric benzoate, naphthenate or stearate.  The catalysts are effective in concentrations from 0.01 to 1.0 weight per cent.  The preferred temperature range is from 50 DEG  to 150 DEG  C. and the reaction time in the order of 24 hours.  The product may be diluted with benzene and hydrogenated to give 2-methyloltetrahydropyran - 2 - yl - tetrahydropyran - 2 - yl - carbinol.  If the carbinol is hydrated prior to hydrogenation the product is 5-methylol-1,5,6,7,11-undecane-pentol.  In examples, acrolein dimer is heated for 24 hours at 120 DEG  C. in the presence of (1) copper naphthenate in xylene solution; (2) copper benzoate; and (3) copper stearate; the product in each case is diluted with benzene and hydrogenated using Raney nickel as catalyst to yield the diol, and tetrahydropyran-2-methanol is obtained as a by-product from the hydrogenation of unreacted dimer.  A comparative example describes the condensation of acrolein dimer in the presence of sodium hydroxide followed by hydrogenation. Specification 667,131 is referred to.

Abstract: 221,460. Siemens Bros. & Co., Ltd., Berry, J., and Peters, C. L. Jan. 24, 1924. Drawings to Specification. Automatic exchange systems; metering.-In an exchange network in which the initial letters of the name of the wanted exchange are dialled to an idle register-controller which translates them into a routing number, if the calling subscriber commences to dial before an idle register-controller has been engaged, the subsequent seizure of a register-controller is prevented. A busy signal may also be given to the calling party. According to the arrangement described, the circuit of the driving magnet of the switch which hunts for an idle register-controller, extends over wipers of a sequence switch associated with the first selector. If the subscriber commences to dial before the seizure of an idle register-controller, the first relapse of an impulse relay completes a circuit which steps the sequence switch to its next position in which the driving circuit of the hunting switch is opened and busy tone sent to the calling party. The invention is shown as applied to a system which is identical with that described in Specification 217,981. Specification 203,759 also is referred to.
