Ethane: Structure, Properties & Uses of C2H6

1 molecule of C 2 H 6 or the molar mass of C 2 H 6 is 30.07 g. Ethane acts as raw material in the production of ethylene through the process of pyrolysis: CH3CH3 CH2CH2 + H2. It can be produced using sodium propionate in the laboratory method. The reaction is: CH3CH2COONa + NaOH → C2H6 + Na2CO3.Web

For example, when the ethylene storage time is 2 h, an ethylene price of 1.8606 US$ kg −1 is required to achieve NPV = 0, which means the project would give a 10 % rate of return on investment. Alternatively, with the current price of ethylene, reduction of the ethanol price to 0.4814 US$ kg −1 is required to get NPV = 0 (Tab. 9 ).Web

A petrochemical product

Currently, the majority of PVC is manufactured by combining ethylene with chlorine. As ethylene is a product of the oil & gas industry, PVC is therefore considered to be a petrochemical product. PVC can also be produced from a range of hydrocarbons including coal, and derivatives of plants such as sugar cane, but this method is not used in Europe.Web

COAL -- A Fossil Fuel
