...constituents of coal gas. It is produced: — 1. By synthesis from its elements. When an electric arc from a powerful voltaic battery passes between carbon poles in an atmosphere of hydrogen, the carbon and hydrogen unite in the proportion to form ethine. 2. By the action of heat upon ethene,... | |
