How can the odor of residual toluene in industrial products be completely removed?
Thread Content
The polyethylene glycol derivatives I produced used toluene as a solvent; after the product was prepared, toluene was removed through vacuum distillation. The water pump was run at 80°C for half a day, yet the odor of toluene wasn’t completely eliminated. The customer has very high requirements regarding the odor of the product, and I couldn’t find a more suitable solvent (primarily because other solvents with lower boiling points result in high recovery losses, making them uneconomical to use). . . I would like to ask the experts for some advice on how to completely remove the toluene solvent from viscous products The requirements aren’t very high; there’s no need for ppm levels – it’s sufficient as long as the taste is not noticeable. I tried using a hose, but it was difficult to completely remove the water introduced. . . I wonder if there’s a better way?
Soak the lamb in water for a night, and by the next day the meat will no longer have a strong smell.... :lol
There are such great things too! I’d like to ask the experts: what kind of adsorbent is it? Is there any name, model, or something like that?
