Additional information

Compilation of viscosity data on 1,2,3 -Trichloropropane (at 20 °C):

 Data source  Viscosity reported
Gerhartz 1985 (i.e. Ullman's Ecyclopedia of industrial Chemistry)   0.25 mPa · s
 Riddick 1985 (Techniques of Chemistry 4th ed.)    2.5 cP *
DIPPR Database 2010 (referring to Mumford 1950)  ca. 2.5 mPa · s
  DIPPR Database 2010 (referring to van Velzen 1972)  ca. 2.2 mPa · s 

* 1 cP = 1 mPa · s

Gerhartz and Riddick are referenced and peer reviewed handbook data, thus both are rated Klimisch 2. However it is assumed that there occurred some flaw concerning the decimal point of the data reported by Gerhartz. The value reported by Riddick is 2.5 cP (= 2.5 mPa · s), and is being considered as the more reliable data point, as the viscosity value given by Riddick is getting supported by two more publications cited in the DIPPR Database (i.e. Mumford 1950, and van Velzen 1972). Therefore, all in all the weight of evidence indicates that the viscosity of 1,2,3 -Trichloropropane is 2.23 mPa · s at 20 °C.
