Patent GB-676601-A (GB)
Title: A process for the production of alkynols
IPC: C07C29/42
Filed: 1950-12-27
Abstract: Alkinols and alkine-diols are prepared by reacting a solution of acetylene or an acetylene hydrocarbon with a solution of an aldehyde or ketone in the presence of copper acetylide or other ethinylation catalyst while maintaining the pressure in excess of 250 lbs. per square inch.  Suitable solvents for the acetylene or acetylene hydrocarbon are acetone, propargyl alcohol, tetrahydrofuran and dioxan, and suitable aldehydes and ketones are formaldehyde, acetaldehyde, benzaldehyde, acetone, methylethyl ketone and acetophenone.  Temperatures up to 200 DEG  C. may be employed when using small catalyst particles in the so-called fluidized catalyst technique.  In an example, a solution of acetylene in acetone and a solution of formaldehyde in water are introduced by means of a proportioning pump into a tubular reaction column packed with copper acetylide catalyst deposited on silica gel, the pressure being maintained at 1,000 lbs. per square inch.  A table is given showing the amounts of propargyl alcohol and butine-diol produced at temperatures of 95 DEG  and 125 DEG  C. and with mol. ratios of formaldehyde to acetylene of 1.67 and 0.8.

Abstract: 537,821. Expelling exhaust gases. MIDDLETON, J. M., and MIDDLETON, O. T. Dec. 4, 1939, No. 31397. [Class 7 (ii)] The expulsion of the exhaust gases is assisted by a small auxiliary cylinder 1 permanently open to the engine cylinder and fitted with a spring - actuated plunger ; the auxiliary cylinder may be arranged co-axially on the head of the engine cylinder, or horizontally at the side of the cylinder, or on the cylinder head as shown in the Figure. In the last-mentioned case, cam means are provided for causing an initial movement of the auxiliary plunger 3, so that the charge compressed in the engine cylinder may act on the plunger and complete its movement to the position shown, compressing the spring 5 ; or the face of the plunger is sloped so as to leave a wedge-shaped clearance when forced towards the left-hand end of the auxiliary cylinder, as indicated in dotted lines. In order to reduce the clearance in the engine cylinder, the face of the main piston 2a may be formed with recesses to accommodate the inlet and exhaust valves 10, 11. A spark-plug or fuel injector 12 is provided on the auxiliary cylinder. In a further modification, the auxiliary cylinder may communicate with the engine cylinder through an intermediate chamber.

An arm 52 is pivoted to the base-plate 51 at the origin O and is marked with a scale of graduation Ae divided in the same way as scales Ah and B. The arc of the circle is graduated with two scales of angles we and wh such that we=tan<SP>-1</SP> (sin #) and wh=tan<SP>-1</SP> (1/sin #), where 0 is the angle which the arm 52, when set at the graduation we or wh on the arc, makes, with the scale B. The drawing instrument is set according to the values of two variables w and d, where 1 tan w=e, for an ellipse or tan w=- for a e hyperbola, e being the eccentricity of the conic section to be drawn and d=ep, where p is the distance of the focus from that directrix for that conic. The angle w for an ellipse may be read off from the appropriate scale we on the are by setting the arm 52 so that it intersects the arc at a point whose ordinate is e, or, alternatively, where a and b the values of the major and minor semi-axes are known by setting the arm 52 so that the graduation on scale Ae indicating the given value of a has as its abscissa the given value of b, whereby sin 6 will equal #a<SP>2</SP>-b<SP>2</SP>/a which equals e. Similarly, since d=ep=b<SP>2</SP>/a =b cos # d may be found by finding the abscissa on scale B of the point on the scale Ae on the arm whose value is b. Similar methods may be used to determine the values of w and d for setting up the drawing instrument to describe hyperbolµ.
