Mitsubishi Chemical Corp. developed a water-based ink composed of photo-chromic-containing capsules and an aqueous polymer binder.46 The average particle size of the capsules containing photochromic spirooxazine and antioxidant was 20 pm. By using this ink composition, cotton clothes could be screen printed. The printed part showed coloration within 10 s when exposed to sunlight and exhibited good fatigue resistance. Furthermore, it bleached within 15 s in the dark, and this process was observed repeatedly. 

The rights to license this technology were given from Chisso to Japan Polypropylene Corp., which is a PP joint venture between Chisso and Mitsubishi Chemical Corp. 

Commercial plants The first commercial plant incorporating CT-BISA with a 70,000-tpy capacity was constructed for Shin Nippon Bisphenol Co., Japan, and has been successfully operated since 1991, in collaboration with Nippon Steel Chemical Co., Ltd. This plant has been revamped by Chiyoda to 95,000 tpy in 1999. A second facility, with 25,000-tpy capacity for Taiwan Prosperity Chemical Corp., Taiwan, has been successfully operated since 1995. A third facility, with 70,000-tpy capacity for Mitsubishi Chemical Corp., Japan, started up in 1998 and has been revamped to 100,000 tpy by Chiyoda in 2000. In 2000, two new contracts have been awarded to CT-BISA Process, i.e., a 100,000-tpy BPA plant by Mitsubishi Chemical Corp., Japan and a 25,000-tpy plant by Bluestar, China-...

As a third compound of this series benzofenap, (15, Fig. 4.4.5) was lunched by Mitsubishi Petrochemical Co. Ltd. (now Mitsubishi Chemical Corp.) and commercialized by Rhone-Poulenc Yuka Agro KK, a joint venture of Mitsubishi Chemical Corp. and Rhone-Poulenc Agro (now part of Bayer CropScience) in 1987 for the rice market. Interestingly, benzofenap is not only applied in Japan as Yukawide but also in Australia as Taipan . The new herbicide was patented 1982 [17] and reported 1991 [18].

The most effective molybdenum-based oxide catalyst for propane ammoxidation is the Mo-V-Nb-Te-0 catalyst system discovered and patented by Mitsubishi Chemical Corp., Japan, U.S.A. (140). Under single-pass process conditions, acrylonitrile yields of up to 59% are reported, whereas under recycle process feed conditions, the acrylonitrile selectivity is 62% at 25% propane conversion (141). Although the latter results show that the catalyst operates effectively under recycle feed conditions, the catalyst system was originally disclosed for propane ammoxidation under single-pass process conditions. The catalyst was derived from the Mo-V-Nb-0 catalyst developed by Union Carbide Corp. for the selective oxidation of ethane to ethylene and acetic acid (142). The early work by Mitsubishi Chemical Corp. used tellurium as an additive to the Union Carbide catalyst. The yields of acrylonitrile from propane using this catalyst were around 25% with a selectivity to acrylonitrile of 44% (143). The catalyst was also tested for use in a regenerative process mode much like that developed earlier by Monsanto (144) (see above and Fig. 8). Operation under cyclic reduction/reoxidation conditions revealed that the performance of the catalyst improved when it was partially reduced in the reduction cycle of the process. Selectivity to acrylonitrile reached 67%, albeit with propane conversions of less than 10%, since activity in... 

This preparation procedure also creates solid-state phases that are key to the performance of the Mo-V-Nb-Te-0 catalyst for propane ammoxidation. High activity and selectivity result when the x-ray powder diffraction pattern shows the presence of specific diffraction lines attributed to two separate phases denoted as Ml and M2 by Mitsubishi Chemical Corp. The diffraction lines assigned to these two phases are given in Table 7 (146). The coexistence of these two phases is viewed as key to the successful functioning of the catalyst. Specifically, the Ml phase is purportedly responsible for the oxidative dehydrogenation of propane to propylene, the key intermediate in the reaction network. This reaction sequence, in which the first step is the formation of a propylene intermediate, is the same as noted previously with other propane ammoxidation catalysts, most notably with the V-Sb-0 catalyst (see above). The M2 phase of the Mo-V-Nb-Te-0 catalyst is reportedly the center for the selective ammoxidation of the propylene intermediate to acrylonitrile. As the first-formed intermediate, propylene is apparently the source of all the observed reaction products. Although a detailed kinetic analysis has not been presented, a cursory report, published in Japan, summarized the kinetic experiments for the conversion of propane and propylene over a...
