the mixture is in solution. water i would expect but am not entirely sure of. can be sure that there are nor heavy metals or chlorine in the mix since h3po3 reacts very strongly with metals esp. the heavier ones, and since there is a huge warning 'do not use if chlorine is over 100 - 300 ppm (big range doncha think)', so, hopefully we have polymaleic and phosphonic and water and thats it. as for a fractional distillation i have my reservations. h3po3 breaks down more readily into h3po4 with heat and especially in the presence of water. i'd also worry about any hot spots that put the temp to 183 which is the thermal breakdown point to phosphinic acid ( i think...that's a lil foggy)... sooooo
where's that leave me and or us? i am thinking a rextal. first i think i will measure volume and weight, then set in dessicating chamber, reduce volume of h2o and re-measure and weigh. from there a somewhat oddish rextal? any thoughts
