A parallel, semi-continuous or continuous, pressure reactor comprising fournor more semi-continuous or continuous reaction vessels for containing a liquidnreaction mixture, each of the four or more reaction vessels beingnpressurizable to a pressure of not less than about 50 psig, at least four liquidnfeed lines in selectable fluid communication with each of the four or morenreaction vessels, each of the at least four liquid feed lines being in fluidncommunication with one or more liquid reagent source vessels, such that onenor more liquid reagents can be selectively fed from the one or more sourcenvessels to each of the four or more reaction vessels during a reaction undernreaction conditions, and. at least one feed-pressurization station pressurizablento a pressure of not less than about 50 psig, at least a portion of each of thenat least four liquid feed lines being in selectable fluid communication with thenat least one feed-pressurization station, such that the one or more liquidnreagents prefeed to the feed-pressurization station under pressure tonprepressurize the portion of the at least four liquid feed lines prior to feedingnthe one or more liquid reagents to the four or more reaction vessels. |
