Sodium Hydroxide → HCID 86648301, compound

Participants

Reaction Steps

A 1.0 M catalyst (referred to in Table 6 below as VTH) can be prepared as follows: (1) Add 218 grams (1.0 M) of technical grade sodium gluconate (2,3,4,5,6-pentahydroxycaproic acid sodium salt) to 700 milliliters of de-chlorinated tap water or equivalent. Mix solution to completely dissolve the sodium gluconate. (2) Add 59 milliliters of 50% sodium hydroxide to the mixture and continue to mix. (3) Slowly add 113 milliliters of 38-40% iron chloride solution to the solution while monitoring pH with continued mixing to form iron-2,3,4,5,6 pentahydroxyhexanoate. The pH of the final solution should be circum-neutral (6.5-7.5). Adjustments back into the circum-neutral range can be made with caustic soda (if below 6.5) or with ferric chloride (if above 7.5).
