Executive summary:

Values Main Study




















Melting point/range Begin End
1st determination59.6 °C (332.8 K) 63.3 °C (336.5 K)
2nd determination59.2 °C (332.4 K) 63.2 (336.4 K)

 


 


Result Test Item


The means of both determinations give the following values for the melting range:


 

















Melting point: 59.4 to 63.3°C (332.6 to 336.5 K) 
Standard deviation:0.28 (begin); 0.07 (end)
Estimated accuracy:± 0.4°C

 


The test item Reaction product of 2-hydroxybenzoic acid, styrene and oxozinc showed a melting range, no melting point. As the test item consists of a mixture, this is considered as normal. No observations were made which might cause doubts on the validity of the study out-come. Therefore, the result of the study is considered valid.

Description of key information
