"Thionyl ester" is also a collector of sulfide ore. The hydrocarbyl amino group in the xanthogen molecule is substituted with "thiourethane", so the "thiourethane" collector is also a derivative of xanthate:
      S S S R'
     / / / /
  ROC—SNa ROC—SH ROC—N—R′′
Sodium xanthate xanthogen "thilyl ester"

In the thioammonia molecule, R which is bonded to oxygen and R' which is bonded to nitrogen may be the same alkyl group or may be a different alkyl group, and R" may be a hydrogen atom or an alkyl group. When the ester-type collector is named, the alkyl group attached to the oxygen in the molecule is first listed, and then the alkyl group attached to the nitrogen is listed, and the sulfur is given to the carbamate to obtain a chemical name. :
Structured chemical name
S C 2 H 5
/ / O-ethyl-N-ethyl (ethyl) ethionine
C 2 H 5 OC-N-H sulfur carbamate
S
CH 5 / C 2 H 5 O-isopropyl-N-ethyl (isopropyl) ethionine
> CHOC-N < sulfur carbamate
CH 3 H

The rest are analogous.
(In the simple name, the words enclosed in parentheses indicate that this group is directly linked to oxygen.) It is obvious that the thiourethane collector is derived from formic acid.
