Patent CA-2137489-A1 (CA)
Title: Method of controlling a photoreaction with a laser beam
Inventor: KIRA MITSUO
IPC: C07F7/18
Filed: 1994-12-07
Abstract: A target is irradiated with a laser beam having an energy of h ~/n, where n is an integer, instead of the photon energy h ~ required for a reaction to proceed using a conventional single-photon excitation method. A desired reaction is selectively induced by the absorption of multiple photons instead of single photons. It is thus possible to induce a photoreaction in which an absorption is carried out in accordance with a selection theory different from that of single-photon absorption, and which is quite different from a photoreaction induced by a single-photon excitation. Namely, a target or reactant is irradiated with a photon energy h ~2 having a wavelength integral times longer than that of the photon energy h ~1 necessary for a photoreaction to proceed. Photon energy h ~2 is either used in place of the photon energy h ~1 necessary for a photoreaction, or together with the photon energy h ~1, to thereby make the reactant absorb the energy equal to the photon energy h ~1, The method is capable of selectively and preferentially inducing a specific photoreaction among various possible, concurrent photoreactions.

Title: Vaporisation of liquids
Inventor: SCOTT JOHN DAVID
IPC: B01F23/10
Filed: 1994-04-14
Abstract: Prior to carrying out a gaseous phase chemical reaction, a liquid phase organic compound which is prone to degrade is vaporised at elevated pressures with the aid of a second compound. In one embodiment of the invention, vaporisation is effected by co-vaporising a mixture of the two compounds in a vaporiser (30) (figure 2). In another embodiments (figures 5-7), the first compound (146, 148) is injected into a hot gaseous stream and undergoes atomisation into droplets which then vaporise within the gaseous stream. The second compound (160,162) is used to assist the atomisation process and/or to sweep atomised droplets of the first compound away from hot surfaces where the first compound would otherwise tend to undergo degradation if the droplets arc allowed to reside in contact with such surfaces.
