calcium stearate removal
hi guys.
im from the rubber glove industry and we are in the midst of developing high alkalinity chlorine based cleaners using sodium hypochlorite as the
chlorine source.
our main formula would be using:-
NaOH - 20wt%
KOH - 5wt%
and Sodium hypo - 25wt%
with the remaining being topped up with water.
this is a typical formula for industrial cleaner to remove calcium stearate from the latex caogulant tanks.
the trouble is, it doesnt seem to work efficiently, even at elevated temperatures of 70C. we cant go up further due to end product issues
anybody here have any ideas how we go about making an alkaline chlorine cleaner which can remove calcium stearate? or any other indgredient that might
be able to help?

How is this connected to amateur chemistry? You are asking here for help in solving a problem you are being paid to solve. Not only that, the problem
is profit related which is the exact opposite to amateur motives.
…there is a human touch of the cultist “believer” in every theorist that he must struggle against as being
unworthy of the scientist. Some of the greatest men of science have publicly repudiated a theory which earlier they hotly defended. In this lies their
scientific temper, not in the scientific defense of the theory. - Weston La Barre (Ghost Dance, 1972)

Really Nicodem ?
Don't you think that crossfertilisation is good? It may even improve the standing of this wonderful, talented community to the outside world, who only
think "breaking bad".
My advice, for stearates, is to find a chelator that is stable in hypochlorite - citraate and edta-ate would be suitable if they are stable in such a
high hypochlorite concentration as 25% Then any Ca salts which would prevent stearates from dissolving can be removed.
Cheers,
Harristotle

<a href="viewthread.php?tid=19143"> | Quote: | On the other extreme, being a professional scientist and a paid researcher does not mean that you can not have honest amateur interests and
participate in the discussions. However, in such case avoid abusing SM for solving problems related to your job, problems which you are paid to
resolve. You can take it as a noble cause to teach what you learned to others who are in need of such knowledge and your efforts will be much
appreciated.
Take notice that discussions motivated by commercial interest and greed have no place on an forum for amateurs. |
