Title: Manufacture of basic 1 : 3-dialkoxy-propanols and 1 : 3-dialkoxy-propanones
IPC: C07D295/096
Filed: 1941-09-25
Abstract: Basic 1 : 3-dialkoxy-propanols are prepared by reacting an epihydrin ether with an alcohol or a phenol there being present in the epihydrin ether or in the alcohol or phenol or in both at least one tertiary amino group.  The propanols as prepared may be oxidized to the corresponding propanones.  In examples (1) 2-Diethylaminomethyl-4-methyl phenol, prepared by the action of formaldehyde and diethylamine on para-cresol, is treated with epichlorhydrin in the presence of alcoholic sodium hydroxide to give 1-(b  : g -epoxypropyloxy)-2-diethylaminomethyl-4-methylbenzene which on treatment with alcohol gives 1-(21-diethylaminomethyl-41 - methyl - phenoxy - 11 -) - 3 - ethoxy - propanol -2.  In a similar manner there may be obtained the corresponding bases 1-(21-dimethylaminomethyl - 41 - methylphenoxy) - 3 - methoxy - propanol - 2, 1 - (21 - dimethylaminomethyl - 41 - methylphenoxy) - 3 - ethoxy - propanol - 2, 1 - (21 - piperidinomethyl - 41 - methylphenoxy) - 3 - methoxy - propanol - 2, 1 - (21 - piperidinomethyl - 41 - methylphenoxy)-3 - butyloxy - propanol - 2. (2) A mixture of epiphenylene and N-hydroxyethyl-piperidine is heated in an autoclave to give 1-phenoxy-3-N-piperidethoxypropanol-2.  On oxidation with chromium trioxide in glacial acetic acid it is converted into the corresponding propanone.  (3) Epiphenylene is heated with N-hydroxyethyl morpholine to give 1-phenoxy-3-morpholinylethoxy-propanol-2.  (4) Epiguaiacoline is heated with diethylamino-ethanol to give 1-(21-methoxyphenoxy - 1) - 3 - diethylamino - ethoxypropanol-2.  Other epiarylines and epialkylalkylines mentioned include epixylenyline o-, and p-epicresylines epiethylines, and epianyline.  Other bases mentioned include methylpropylamino- or methylisopropylamino-ethanol, and methylisobutylamino-, or ethyl - tert. - butyl - amino-ethanol. (5) Epiphenylene and 2 : 3-dihydroxypropyl-1-diethylamine are reacted to give 1 - phenoxy - 3 - (31 - diethylamino - 21 - hydroxypropyloxy-1-g -propanol-2.  (6) b -naphthol is reacted with epichlorhydrin in the presence of potassium hydroxide, and the epi-b -naphthyline so produced is reacted with triethanolamine to give 1-(b -naphthyloxy-3-dihydroxyethyl) - aminoethoxy - propanol - 2.  (7) a -epinaphthalene is reacted with N-hydroxyethyl-morpholine to give 1-a -naphthyloxy-3-N-morpholinyl-ethoxypropanol-2.  Specifications 546,286 and 555,192 are referred to.

Abstract: 826,347. Machinery safety devices. LOTUS Ltd. May 7, 1956 [May 6, 1955], No. 13127/55. Class 80 (4). In a clicking press in which the engagement of the clutch is effected through electromagnetic means under control of main switch means associated with a gripping member on the presser beam and additional switch means positioned so that they cannot be operated by the same hand as that employed on the gripping member the switch means are so arranged that they must both be restored to their circuitbreaking positions before a repeat operation of the press can be carried out. This is effected by an interlocking circuit as shown. The energization of a clutch-operating solenoid 15 by a high-voltage current source to motor 19 is controlled by a low-voltage coil 211 as described in Specification 663,477 the arrangement being such that after energization of the solenoid 15 a single stroke of the press is effected and for a second stroke the solenoid 15 must be first deenergized and then re-energized. The energization of solenoid 15 is effected through closing contacts 21 controlled by low-voltage coil 211 which is energized by the closing of contacts 141, 142 of a relay 14 which is in turn energized by the closing of the contacts 131, 132 of main switch 13 and either the contacts 171a, 171b of switch 171 or the contacts 172a, 172b of switch 172. The contacts 141, 142 also provide independent circuits for energizing the relay 14 through either the main switch or the relevant auxiliary switch so that both of these switches must be opened to de-energize the relay 14 and hence the solenoid 15. Stop and start push-button switches 18a, 18b are provided for the motor 19 and the low-voltage supply of current is derived from a step-down transformer 20. Specification 667,731, [Group VIII], also is referred to.
