Key result

Boiling pt.:

ca. 116.17 °C

Atm. press.:

ca. 760 mm Hg

The boiling point/boiling rangeof TYZOR ACtivate 422was determined using Siwoloboff method.

The boiling point of TYZOR ACtivate 422was 389.35, 389.25and 389.35K at normal atmospheric pressure (760 mm Hg).

The mean boiling point of TYZOR ACtivate 422was 389.32± 0.06K (116.17 ± 0.06°C) at normal atmospheric pressure (760 mm Hg) [TABLE 1].

The boiling point range of TYZOR ACtivate 422 was 115.80-116.20 °C at normal atmospheric pressure (760 mm Hg) [TABLE 1].

Repli-cation	Temperature of Initiation of Bubble Formation (°C)	Temperature at which Continuous String of Bubbles were Observed (°C)	Boiling Point Range	Boiling Point
				(°C)	Kelvin (K)
R1	115.90	116.20	115.80-116.20	116.20	389.35
R2	115.90	116.10		116.10	389.25
R3	115.80	116.20		116.20	389.35
Mean				116.17	389.32
Standard Deviation				0.06	0.06
Typical Calculation
Boiling Point [in Kelvin (K)]=Observed Boiling Point(°C) + 273.15                                                          =116.20 + 273.15                                                          = 389.35

Conclusions:

The mean boiling point of TYZOR ACtivate 422 was obsevved by Siwoloboff method and found to be 116.17 ± 0.06°C at normal atmospheric pressure (760 mm Hg)

Executive summary:

The mean boiling point of TYZOR ACtivate 422was 389.32± 0.06K (116.17 ± 0.06°C) at normal atmospheric pressure (760 mm Hg)
