“…It was first proposed that acetylene can generate benzene through cyclotrimerization (3C 2 H 2 → C 6 H 6 ) in 1866. 23,24 The researchers found that acetylene ring trimerization can take place on a variety of materials, such as Ni/SiO 2 , 25 Pd−Au, 26 Pd, 27−29 TiO 2 , 30,31 V 2 O 5 , 32 Pt− Sn, 33,34 and Cu. 35,36 Earlier works have determined the reaction network diagram of benzene, which consists of eight elementary reactions.…”

The reaction network of benzene as a byproduct in the production of vinyl acetate from the acetylene process was further improved by density functional theory (DFT). The mechanism of the byproduct acetaldehyde as a competitive reaction was also systematically studied by DFT. Kinetic Monte Carlo (KMC) was used to further study the main reaction and various side reactions in the process of producing vinyl acetate from acetylene. The effects of temperature, pressure, and molar ratio of acetylene/ acetic acid on the reaction process were investigated. Under the process conditions of 453 K, low pressure, and low molar ratio of acetylene/acetic acid in the range of 2−2.6, the formation of byproduct benzene is inhibited.

“…To explain these observations, and for a variety of other reasons, it was suggested by Lind that an essential difference between photochemistry and radiation chemistry lay in formation in the latter of ions around which molecules could cluster and there react. This view is not now generally accepted (57).…”

Education seems always to be in the midst of a crisis-or even simultaneously in several. One of those in which it is involved just now does nothappily-particularly concern science education. But although the heat has been generated in the social and political areas there is no telling when the fever will spread to others. It came to a head in the recent "Pasadena incident," the details of which need not be recounted. A superintendent was brought in to reorganize and improve the school system. He proved too "progressive" for his constituency; the principal complaint was that his innovations ignored the rights of the home and prepared pupils for a life of social regimentation rather than one of intelligent individualism. Bloodhounds thought they detected a vague scent of communism. Public furor and the failure of a bond issue to implement the new program led to the superintendent's resignation. The wild debates brought out the clear issue: to what extent is the younger generation to be subject to the "educational experts"; what, if anything, shall the home and the rest of society have to say about educational policies, the curriculum, etc.? This is not a new issue, by any means.The question is always being asked: "Who tells the teacher what to teach?" The school and the home are not always at peace, although society must of necessity charge the school with the responsibility for education of the child.
