The nature of "thiourethane" collectors

"Thionyl ester" collector is an oily liquid with a special odor. Its specific gravity is slightly lower than that of water. Its solubility in water is relatively small, but it is good enough in the pulp for tens of grams per ton of mine. Dispersibility, so it can be directly used in flotation tank or agitation tank.
"Thionyl ester" collectors exist in the form of "thiol" (C=S) in the acidic and neutral medium, but in the alkaline medium, they can be transformed from the "sulfur" formation. It is a thiol type, so it can be considered that the "thiourethane" type collector has weak acidity:
     S SH
    / /
ROC-NHR'←→ ROC==N-R'
(acidic or neutral medium) (alkaline medium)
This tautomerism of "thiourethane" collectors has been demonstrated by absorption spectroscopy.
In the 1-20% NaOH solution, the following conversions may occur:
S S- S
/ / /
ROC—NHR′←→ [ROC == NR′]←→ [ROC—N—]

Farmers feeding the world. Our planet faces urgent challenges to feed the burgeoning
population with the finite resources. Pesticides is playing more and more
important role in global agriculture production. Yihe-chem Co., Ltd strives to
