METHOD FOR CONDUCTING LABORATORY PHYSICO-CHEMICAL RESEARCH PROCESSES WHILE PRODUCING CELLULOSE Russian patent published in 2022 - IPC B01J3/04 D21C3/02 D21C7/00 

FIELD: physical and chemical processes.

SUBSTANCE: invention relates to a method for conducting physico-chemical processes at high temperature in laboratory conditions and is intended primarily for conducting research using aggressive media. Method for conducting laboratory physico-chemical research processes while producing cellulose includes boiling chips in a container at an elevated temperature by means of a thermostating system for producing cellulose, wherein the chips are boiled at an elevated temperature in containers of stainless steel ampoule reactor vessels with threaded-on caps at a working pressure of 1.5 MPa in the battery autoclave filled with a glycerine-based stirred heat carrier heated by a spiral electric heating cable in the form of a heating element installed on the outside of the autoclave body; the containers of the ampoule reactor vessels are set on a metal stand with holes matching the shape of the thrust part of ampoule reactor vessels arranged evenly over the area.

EFFECT: increase in the reliability of laboratory physico-chemical research processes.
