Abstract:
A method of processing reaction mixtures in parallel, comprising: forming chemical reaction mixtures in a plurality of reactor vessels of a parallel reactor apparatus said apparatus comprising sensors for providing measured values relating to chemical reactions in said reactor vessels, and a processor for receiving data relating to said measured values; sealing the reaction mixture in each reactor vessel against fluid communication with the other vessels and at a pressure different than ambient pressure; injecting a fluid into at least one of the reactor vessels while the reaction mixture in said at least one vessel is sealed and at a pressure different than ambient pressure; agitating the reaction mixtures for at least a portion of the sealing step; and using the processor to receive said data relating to said measured values of the chemical reactions in said reactor vessels.
Abstract:
A method for parallel processing of a plurality of reaction mixtures and for monitoring the consumption or production of a gas-phase component of the reaction mixtures, the method comprising reacting the reaction mixtures in a plurality of vessels such that the pressure in the vessels changes as the gas-phase component of the reaction mixtures is consumed or produced, sensing the pressure within the vessels, passing the gas-phase component of the reaction mixture into or out of the vessels in response to the pressure sensed within the vessels, and recording the pressure changes within each of the vessels.
