22363 results about "Alkyl" patented technology

In organic chemistry, an alkyl substituent is an alkane missing one hydrogen. The term alkyl is intentionally unspecific to include many possible substitutions. An acyclic alkyl has the general formula CₙH₂ₙ₊₁. A cycloalkyl is derived from a cycloalkane by removal of a hydrogen atom from a ring and has the general formula CₙH₂ₙ₋₁. Typically an alkyl is a part of a larger molecule. In structural formula, the symbol R is used to designate a generic (unspecified) alkyl group. The smallest alkyl group is methyl, with the formula CH₃−.
