Hexane, exposion properties

People living near hazardous waste sites containing //-hexane or near its manufacturing, processing, or storage facilities could potentially be exposed. Because of the chemical properties of //-hexane, the most likely way a person would be exposed is by breathing in air contaminated with //-hexane. A less likely way for a person to be exposed is by drinking contaminated private well water.

We have studied about the treatment of aggregated galloalxmino-silicate (ZSM-5 type zeolite) with KOH solution. The suitable KOH treatment of TPA-Si-Al-Ga is found to be a very valid preparation to disperse the aggregated zeolites Into small particles and expose the external surface of unit crystals without changing other properties. Furthermore, the suitable KOH teratment of TPA-Si-Al-Ga increased the catalyst life in aromatizatlon of n-hexane.
