Scope
GB/T 36692-2018 is the English-translated version of 工业用顺式-1,3,3,3-四氟丙烯[HFO-1234ze(Z)].
GB/T 36692-2018 is the Chinese product standard for industrial cis-1,3,3,3-tetrafluoropropene, HFO-1234ze(Z) or R1234ze(Z), with the structural formula CF3CH=CFH and a relative molecular mass of 114.04.
It covers the product made from tetrachloropropene, pentafluoropropane and similar raw materials reacted with anhydrous hydrogen fluoride over a catalyst, or by isomerization of trans-HFO-1234ze(E), and then purified.
It specifies the requirements, including a colourless transparent liquid free of visible solid particles, together with the test methods, inspection rules, marking, packaging, transport and storage.
The referenced methods include gas chromatography, sampling of gaseous chemical products, and the determination of non-condensable gases, chlorides, acidity, evaporation residue and moisture in fluoroolefins, plus the filling of liquefied gas cylinders. It was issued on 17 September 2018 and has applied since 1 January 2019.
