how to make n-heptane from acetone and methyl alcohol?

Try to convert acetone to alchols by different reduction process with reducing agents like LiAlH4. And Then covert the alcohols to Hydro Carbons by heating or further reduction process.

A direct reduction of alcohols to the corresponding alkanes using chlorodiphenylsilane as hydride source in the presence of a catalytic amount of InCl3 showed high chemoselectivity for benzylic alcohols, secondary alcohols and tertiary alcohols while not reducing primary alcohols and functional groups that are readily reduced by standard methods such as esters, chloro, bromo, and nitro groups.
