DETAILED DESCRIPTION - Production of 1'-acetoxychavicol acetate comprises generating p-acetoxyl benzaldehyde using p-hydroxy benzaldehyde and acetic anhydride, generating p-(1-hydroxy-2-propylene)-acetoxyl using p-acetoxyl benzaldehyde and vinyl Grignard reagent, and generating 1'-acetoxychavicol acetate crude product using p-(1-hydroxy-2-propylene)-acetoxyl and acetic anhydride; and separating, refining and drying to obtain 1'-acetoxychavicol acetate refined product. The vinyl Grignard reagent comprises vinyl magnesia, vinyl magnesium bromide, vinyl magnesium iodide. The method uses multifunctional reactor having special reactor bottom valve and refining device that is a filter. The multifunctional reactor comprises reactor, bracket, and electric heating magnetic stirrer. The reactor is a cylindrical barrel of which the upper and lower parts are provided with semi-spherical top cover and semi-spherical bottom cover. The top and bottom covers are connected to the reactor through 2 suspension link bolts on both sides of the reactor. A disc ring groove filter board is between the top cover and reactor. A sealing ring is between the disc ring groove filter board and the top cover and the reactor. A body of the reactor has insulating interlayer interconnected to a top cover insulating interlayer and a bottom cover insulating interlayer, respectively. A coolant inlet is on a side of the lower part of the reactor close to the bottom cover and interconnected to the insulating interlayer, while a coolant outlet is on a side of the upper part of the reactor close to the top cover and interconnected to the insulating interlayer. A feeding port and a distiller interface are on upper part of the reactor close to the disc ring groove filter board and interconnected to the reactor. A temperature measurement port, an inflation port, and a sampling port are interconnected to the reactor and on the lower part of the reactor close to the bottom cover. A viewing window is on the inflation port on lower part of the reactor. A magnetic stirrer is in the reactor. The bracket comprises rotating shaft, bottom board and universal castor. The rotating shaft is on top of the bracket. The reactor is on the bracket through the rotating shaft. The electric heating stirrer is on the bottom board of the bracket. The universal castor is under the bottom board of the bracket. The reactor can be rotated for any angle through the rotating shaft. A diameter of the ring groove filter board is not larger than a maximum diameter of the top cover. The special reactor bottom valve comprises valve body, connection port between the valve and reactor bottom, valve cavity, plunger, thread shaft, locating groove, central locating board, locating nut, hand wheel, locking nuts, discharging port, sealing ring, and quick clamp. The plunger is in the valve cavity and connected to the thread shaft. The locating groove is on the thread shaft fixed in the cavity through the central locating board, the locating nut and locking nuts. The hand wheel is in the bottom of the valve body and in connection with the bottom of the valve body and the thread shaft through the locating nut and locking nut. The discharging port is on a side of the valve body and its outlet is between the central locating board and the connection port between the valve and the reactor bottom. The outlet is also interconnected to the valve cavity. The plunger is sealed with the valve cavity through the sealing ring. The valve cavity is convenient for dismounting and cleaning by the quick clamp. The hand wheel can be replaced by a pneumatic, electric or hydraulic device. The special filter comprises filter top cover, ring groove filter boards, filter bucket and filter bottom cover. The filter top cover has feeding pipe, inactive gas feeding pipe, inactive gas discharging pipe, coolant outlet, coolant return pipe and temperature measuring meter. The filter top cover has insulating layer and interlayer. The filter bucket is on the lower part of the filter top cover and provided with insulating layer, interlayer, external metal plate, middle metal plate, and internal metal plate. The filter bottom cover is on the lower part of the filter bucket and provided with discharging pipe, coolant inlet, insulating layer, and interlayer. The filter top cover is semi-spherical and is on the upper part of the filter bucket through bolts. The ring groove filter board is disc-shaped and provided between the filter top cover and upper part of the filter bucket. The filter bucket is cylindrical and its lower part is in connection with the filter bottom cover through bolts. The filter bottom cover is inverted semi-spherical. The feeding pipe penetrates the filter top cover and is installed in its center. A liquid nozzle is on the port of the feeding pipe penetrating the inner spherical surface of the filter top cover. There is a distance from the liquid nozzle and the ring groove filter board to the inner spherical top surface of the filter top cover. The coolant outlet and temperature measuring meter are on a side of the filter top cover around the feeding pipe. The inactive gas feeding pipe is on the other side of the filter top cover, and penetrates the inner spherical surface of the filter top cover. The coolant return pipe is on the other side of the coolant outlet and between the filter top cover and upper part of the filter bucket. The coolant return pipe is interconnected to the filter top cover insulating layer, the filter bucket insulating layer and the filter bottom cover insulating layer. The filter bottom cover is on the lower part of the filter bucket through bolts. The ring groove filter board is disc-shaped and between the filter bottom cover and filter bucket.
