Question about the specific heat capacity data #25

Closed Zhenetb closed 2 years ago

Zhenetb commented 2 years ago

HI, I would like to ask a question about the specific heat capacity data, the CAS No. of some compounds in the 4 cvs files is in date format, such as: "CH2Cl2, dichloromethane, 1975-09-02 00:00:00,...", and it should be "75-09-2". I think it may be caused by data conversion, it needs to be corrected from the original data.

Thank you for letting me know about this. It will take a while to correct but I'll let you know when it has been fixed.

The CAS numbers were exported from the Knovel (https://app.knovel.com) database for Yaws' Critical Property Data for Chemical Engineers and Chemists. The data presented online is correct but when you export it as Excel it incorrectly formats some of the CAS numbers. There is an option to export the data as CSV but it incorrectly formats the CAS numbers too. So I'll have to go through the files in chemics and fix the CAS numbers.

CAS numbers in the following CSV data files need to be checked and fixed:

@Zhenetb All of the CAS numbers should be fixed in the dev branch. Please check the CSV files in that branch and let me know if you see anything else that needs to be fixed.

This issue should be fixed in the latest version which is v22.8.
