I would like to react sorbitol (sugar alcohol) with HCl 5% in a reactor under the following conditions: Temperature = 140 - 160 °C Retention time = 30 - 40 minutes pH actual mixed raw material = 0.4 - 0.5 Conductivity mixed raw material = 220 ms/cm The reactor will be heated by coil or steam jacket. What material of construction do you suggest to build the reactor? Where we can buy it?
Have an insight or suggestion?

Re: What MOC is suitable for running reactions containing 5% hydrochloric acid?11 November 2010 at 1:29pmThere are not many choices for materials of construction that are suitable for running reactions containing 5% hydrochloric acid at 140 to 160 °C. Running the reaction in a glass reactor or a glass-lined reactor would be the obvious choices. If a metallic alloy is preferred, the only one I can think of that would work is tantalum. The corrosion resistance of tantalum is very similar to glass. Unfortunately, tantalum is very expensive. I am sorry but it is our policy not to make recommendations regarding specific suppliers or manufacturers of equipment. If you don't know where to start, an Internet search should get you some answers pretty quickly.
