Preparation of Alkanes Organic Chemistry Tutorial
As stated earlier, the most important source of alkanes is natural gas and crude oil. Alkanes are separated in an oil refinery by fractional distillation and processed into many products. The Fischer–Tropsch process is a method to synthesize liquid hydrocarbons, including alkanes, from carbon monoxide and hydrogen. This method is used t… WebSynthesis of Alkanes Laboratory Preparation 4 •Reduction (deoxygenation) of aldehydes and ketones also provides access to hydrocarbons. •One of the most common methods for deoxygenation of aldehydes and ketones is the Wolff Kishner reduction. •It involves heating an aldehyde or ketone with hydrazine in the presence of a base (KOH). bit and bridle tack shop
