hydrogen sulfide

Homogenous reaction between hydrogen sulfide and elemental lead vapor removes hydrogen sulfide efficiently as the hot coal gas left the carbonizer.

气态铅和化氢在离开炼焦室时，由于煤气降低温度，又生化铅。

So long as their balance remains undisturbed, the oxygenated and hydrogen sulfide–saturated waters stay separated, and their interface, known as the chemocline, is stable.

直到衡、不互相干扰，充氧海水与饱和化氢海水彼此分隔，而且两者间「化变层」也是稳定。

With hydrogen sulfide and tetrapropylene as raw materials, TDM was synthetized by the one step process in the presence of acidic ion exchange resin.
