Key result
Boiling pt.:
ca. 126.27 °C
Atm. press.:
ca. 760 mm Hg

The boiling point/boiling rangeof TYZOR AC 436 was determined using Siwoloboff method.

The boiling point of TYZOR AC 436 was 399.55, 399.55and 399.45K at normal atmospheric pressure (760 mm Hg).

The mean boiling point of TYZOR AC 436 was 399.52± 0.06K (126.37 ± 0.06°C) at normal atmospheric pressure (760 mm Hg) [TABLE 1].

The boiling point of TYZOR AC 436 was 119.60-122.80 °C at normal atmospheric pressure (760 mm Hg) [TABLE 1].

Typical Calculation

Boiling Point [in Kelvin (K)]=Observed Boiling Point(°C) + 273.15

                                          =126.40 + 273.15

                                          = 399.55

Conclusions:
The mean boiling point of the TYZOR AC 436 was observed by Siwoloboff method and was found to be 126.37 °C at normal atmospheric pressure i.e. 760 mm Hg.
Executive summary:

The mean boiling point of the TYZOR AC 436 was observed by Siwoloboff method and was found to be 126.37 °C at normal atmospheric pressure i.e. 760 mm Hg.
