The Isomerization of Safrole: A Review - [/a>
The isomerization always gives a mixture of both cis- and trans- isomers of the propenylbenzene (approx 30:70 using standard hydroxide ion alyzed isomerization).The trans-propenylbenzene is thermodynamically more stable than the cis-propenylbenzene, so with longer reaction times, the ratio of the trans-isomer is increased in respect to the cis.

Calcium carbide was identified in 1862 and like potassium carbide, reacted with water to form acetylene. It took until the 1890s before a way was found to make calcium carbide and thus acetylene economically and by 1895 calcium carbide plants were operating in the England, France and the US, followed by plants in Norway and Switzerland.
