Conditions:
Room Temp: 6 - 51 °C
Compilers:
Methodology:
(a) A large sample of (1) containing a slight excess of (2) was shaken at a given tempreature and then allowed to stand in a water bath at this temperature for 24 hr to ensure complete separation of the two phases before withdrawal of sample of the rich phase for titration of the water present with the Karl Fischer reagent.
(b) Duplicate determinations gave cloud points agreeing within 1 °C, except in the case of 0.120 g(1)/100 g solution where the agreement was within about 3 °C. Cloud points at 0.040 (1)/100 g solution were very faint. No more detals were reported.
Sample Information:
- source not specified; fresh samples; used as received.
- not specified.
Measurement Errors:
Ambient temperature: (b) ±1 to ±3°C.
Mass concentration (m/v) (1): (a) ±1.5% (from two determinations)
System Components:
- Styrene, $\ce{ C8H8 }$; [100-42-5] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
