Japan and China. During the 1980s, acetylene demand in Japan suffered a significant decline. Chemical use declined from over 100,000 to 42,000 t, acetylene black production declined from 20,000 to less than 10,000 t, and industrial use went from 42,000 to 30,000 t. Thus, based on 1990 estimates, Japan has an excess capacity for acetylene production with capabiUties for 247, 000 t/yr and a demand of only 82,000 t.

Besides the T-cyclopropanes, T-butenes and T-pentenes, several highly unsaturated tritium-labeled products, including acetylene, allene, propyne and 1,3-butadiene were observed in the hot T reaction with EC and DMC. Except for T-acetylene, whose yield is about 10 % of the substituted parent molecule, the yields of the other products are very low.
