Title: Production of gamma-lactones
Inventor: LACEY RICHARD NORMAN
IPC: C07D307/33
Filed: 1953-03-18
Abstract: a -Aceto-g -lactones of the formula <FORM:0740993/IV(a)/1> are prepared by reacting tertiary alkyl (C4-C6) esters of acetoacetic acid with epoxides of the formula <FORM:0740993/IV(a)/2> or derivatives (e.g. chlorhydrins) which generate them under the reaction conditions; the process is carried out in an aqueous solution of an alkali metal hydroxide between -10 DEG  and +10 DEG C. (preferably -3 DEG  C. to +3 DEG  C.); in the formul  R is hydrogen, alkyl, alkenyl, aryl, aralkyl, alkoxy-alkyl or aryloxy-alkyl.  The epoxide or chlorhydrin and the acetoacetic ester may be added to the alkali, or alternatively the latter two may first be reacted to form the sodium derivative of the ester.  The two organic reactants may be used in equimolecular proportions or up to 50 per cent excess of one may be taken.  The reaction mixture is agitated continuously.  The lactone is isolated by neutralization of the reaction mixture with an acid, extraction with a water-immiscible solvent (e.g. toluene), flash distillation to remove water and some of the solvent and tertiary alkanol, and finally fractional distillation.  Examples show the production of (1) a -aceto-g -butyrolactone from ethylene oxide and t.-butyl acetoacetate; (2) a -aceto-g -valerolactone from propylene oxide and t.-butyl or t.-amyl acetoacetate; (3) a -aceto - g  - ethoxymethyl - g  - butyrolactone from glycidyl ethyl ether and t.-butyl acetoacetate; and (4) a -aceto-g -phenyl-g -butyrolactone from styrene oxide and t.-butyl acetoacetate.  Other groups specified for R are ethyl, n-propyl, isopropyl, n-butyl, t.-butyl, n-hexyl, methoxymethyl, 2-methoxypropyl, 1-isopropoxyhexyl, phenoxymethyl, 1-phenoxyethyl, o-toloxymethyl, tolyl, xylyl, benzyl, o-methylbenzyl, m-ethylbenzyl, p-isopropylbenzyl, vinyl, allyl, crotyl and 1-pentenyl.  The products may be hydrolysed with sulphuric or hydrochloric acid to the corresponding keto-alcohols or keto-chlorides respectively, e.g. 5-hydroxyhexan-2-one (R=methyl) or 5-chloro-pentan-2-one (R=4) which are useful intermediates.

Title: Solid state display device
IPC: G02F1/17
Filed: 1969-02-12
Abstract: 1,205,902. Light modulators and deflectors. BENDIX CORP. 12 Feb., 1969 [19 Feb., 1968], No. 7488/69. Heading H4F. A semi-conductor device which transmits and absorbs light as a function of a voltage applied thereto and in accordance to the Franz-Keldysh effect comprises a wedge 1, Fig. 1, of transparent non-conductive material (glass) having a semiconductor layer 5 (cadmium sulphide) and transparent conductive layers 6 and 8 (tin oxide). In operation, an electric potential is applied across layers 6 and 8 and due to the wedge shape of the device the electric field produced varies as a function of the distance between the layers 6 and 8 thus causing the optical absorption band of the semi-conductive material of layer 5 to shift when the electric field strength is sufficient to cause it to shift so that a portion of the semi-conductive material will absorb light of a wavelength that at a lesser electric field strength it would normally transmit. For cadmium sulphide, transmission or absorption of light having a wavelength lying between 5100 and 5200 angstrom units depends on the absence or presence respectively of a strong electric field. By combining two such devices together to form a rectangle having conductive layers 8 and 27, Fig. 2, on each outer face and conductive material 6 in between two layers of semi-conductor material 5 and 24 sandwiched between the two wedges 1 and 23, transmission of a band of light 49 results, the position of which may be displaced by adjusting the movable arm 39 of potentiometer 37 and the thickness of which is determined by the value of resistor 33. By arranging two such combinations of Fig. 2 in line, one being rotated through 90 degrees with respect to the other, Fig. 3 (not shown), transmission is only effected where the two bands of transmission intersect thus forming a rectangular area of transmission whose size and position may be varied as in a conventional cathode ray tube.
