Reactor
The petroleum chemist now connects an unreactive paraffine (isobutane) to a reactive d e f i n e hydrocarbon (isobutylene) to form 2,2,4 trimethyl penxane (100 octane aviation fuel). Concentrated sul phuric acid is the active agent w h i c h j o i n s t h e two together. The process is called alkylation. The petroleum industry uses Sulphur and its compounds in various ways. Sulphuric acid has long been used in refining kerosene, gasoline, and lubricating oils. Sulphur dioxide is also used as a refining agent and

can also be combined with petroleum prod ucts to form plastics. Sulphur as such is used in refining gasoline and in making cutting oils and extreme pressure lubricants.
