Method and apparatus for evaluating hydrogen chloride evolution as a function of temperature

A method of constructing a system including a flask having a plurality of mouths for evaluating hydrogen chloride as a function of temperature, the method comprising:

• providing a heating mantle on a lifting platform;
• securing the flask on top of the heating mantle, wherein the flask includes paraffin oil;
• adjusting a height of the lifting platform;
• applying silicone grease to a portion of a stirring rod to facilitate passage of the stirring rod through a hole in a first connector, wherein a propeller is coupled on the stirring rod;
• inserting the stirring rod through the hole in the first connector;
• connecting the stirring rod to a stirring motor;
• after the stirring rod is inserted through the hole in the first connector, inserting the first connector into a first mouth of the flask;
• checking alignment of at least one of the heating mantle, the flask, the propeller, the stirring rod, or the stirring motor;
• connecting a first end of a gas-dispersing tube to the flask;
• fitting a hose to a second end of the gas-dispersing tube, wherein the hose is configured to allow inert gas to pass through the hose and the gas-dispersing tube into the flask;
• wrapping a gas conducting tube with a first heating tape;
• attaching the gas-conducting tube to the flask;
• wrapping at least one of the plurality of mouths of the flask with a second heating tape;
• electrically connecting the first heating tape and the second heating tape with a temperature control device;
• attaching a first end of a Polytetrafluoroethylene (PTFE) hose to a second end of the gas-conducting tube;
• connecting a second end of the PTFE hose with a separating funnel including a sintered glass tube;
• providing the sintered glass tube of the separating funnel into a 250 ml beaker with a predetermined amount of deionized water;
• and
• connecting a first temperature sensor to the flask such that a first end of the first temperature sensor touches the paraffin oil.
