The invention relates to a use of a fluorination gas, and the elemental fluorine (F.sub.2) is present in a high concentration, for example, in a concentration of elemental fluorine (F.sub.2), especially of equal to much higher than 15 or even 20% by volume, and to a process for the manufacture of a fluorinated compound by direct fluorination employing a fluorination gas, wherein the elemental fluorine (F.sub.2) is present in a high concentration. The process of the invention is directed to the manufacture of a fluorinated compound, for the exception of fluorinated benzene, by direct fluorination. Especially the invention is of interest in the preparation of fluorinated organic compounds, final products and as well intermediates, for usage in agro-, pharma-, electronics-, catalyst, solvent and other functional chemical applications. The fluorination process of the invention may be performed batch-wise or in a continuous manner.

The present invention relates to a synthesis method and synthesis reactor of high-selectivity 2-methylallyl chloride by taking isobutylene and chlorine gas as raw materials and performing a gas-phase chlorination reaction in a microchannel reactor with a cooling surface. The isobutylene and the chlorine gas are reacted in a T-shaped microchannel reactor, and the mixing speed is extremely fast. Meanwhile, the huge heat exchange area per unit volume can ensure that the reaction proceeds stably at a substantially constant temperature and has good controllability. Therefore, side reactions caused by excessive local temperature can be effectively suppressed, the reaction selectivity is high, and no coking phenomenon occurs.
