Abstract: PROBLEM TO BE SOLVED: To reduce the harmful effect of trimethyl amine in the production and the cost required for the treatment by treating the produced trimethyl amine by using hydrogen peroxide at the time of the disposal of a by-product in the production of optical fiber. SOLUTION: In the case of disposal of a by-product containing

Abstract: It has been found that in sol-gel processes utilizing TMAH, it is possible to treat a trimethylamine (TRIMA)-containing solution with hydrogen peroxide to form trimethylamine oxide - (CH3)3N -O- (TRIMAO), a water soluble compound which is less volatile and less odorous than TRIMA, and which is capable of being sent to a standard wastewater treatment plant. The hydrogen peroxide is generally added to the TRIMA-containing solution in a H2O2:TRIMA ratio of at least 3:1, advantageously at least 10:1. Because of the resultant TRIMAO solution's ability to be sent to a standard wastewater treatment facility, improved productivity and lowered expense of the overall fiber fabrication process are obtained. The invention is also suitable for treatment of triethylamine.
