Close Embrace} {shed 1:1:1 mixture by weight of sodium carbonate or calcium carbonate, clay cat litter (bentonite), and sand. When the boron trifluoride complex was absorbed, scoop mixture into sulphuric acid a plastic bucket, and in smoke hood, slowly add the mixture to a bucket of cold water. Let stand for 24 hours. Check the pH solutions and neutralize if necessary with sodium carbonate. Filter the solution leakage. Consider the solid residue as normal failure 5 Waste Disposal Party Pack. Place in a separate labeled container for recycling or disposal. Small quantities. Wear nitrile rubber gloves, laboratory coats and eye protection. In smoke hood, pour the boron trifluoride complex in a large evaporating dish. Cover boron trifluoride complex with additional solid sodium carbonate or calcium carbonate. When the reaction is awake, very slowly add the mixture to a bucket of cold water. Let stand for 24 hours. Check the pH solutions and neutralize if necessary.
