Description of the Invention (2) Zone. It has been found to have disadvantages with known methods; it provides lower yields or significant amounts of reaction by-product formation, and its subsequent products cause soiling. Scale-up has been found to be difficult. As allyl teeth gradually become more valuable, there is an incentive to improve yields and reduce the production of side-reaction products. As a result of active research, improved methods have been found that suffer less Disadvantages of known methods.

In the reactor assembly shown in FIG. 2, the ratio of the maximum outer length of the ring reactor to the diameter of the tube constituting the ring reactor is in a range from 30 to 50, and the maximum outer width of the tubular ring reactor is ^ ^ The range is from 3 to 5. ^ Printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs:: (Please read the precautions on the back before filling this page) The outside of the better tubular ring reactor is the largest The ratio of the length to the diameter of the upper loop reactor is in the range from 35 to 45. The present invention is illustrated by the following examples, but its scope is not exemplified. The paper size is suitable for Guancai County (CNS) -11 482752 A7 B7 V.
