Claim 7:
8. The reaction system according to claim 6, wherein the reaction effluent refining unit comprises a self-vaporization separator and a preliminary acid-hydrocarbon separator,
wherein a coalescing internal member is arranged at an upper part of the self-vaporization separator for vaporizing butane and separating a reaction product from an acid phase, and an acid-hydrocarbon phase homogenizer is arranged at a lower part of the self-vaporization separator, and
where the preliminary acid-hydrocarbon separator is used for performing a primary separation of acid and hydrocarbon, a majority of the separated hydrocarbon phase is recycled, and a minority of the hydrocarbon phase is optionally subjected to a further coalescence-deacidification separation.
