Friday in chaos =(

The lab work this morning was in chaos. I was totally blur and have no idea of what I have been doing for the whole morning. The crystal structure of endo-7-oxabicyclo[2.2.1]hept-5-ene-2,3-dicarboxylate anhydridee carbonyl (what a looong name!!) of the Diels-Alder reaction between furan and maleic acid did not appear as it should be =( I have to spend two hours to make the crystal structure of endo adduct visible, and totally dry.

While at the same time, I have to start another experiment on extracting piperine from black pepper. Then time is running out and I was unable to determine the endo adduct's boiling point and also the TLC result. Will have to wait until next week then. For next lab, the piperine that I have extracted will also be needed to add in some other chemicals, and it is hoped (yes, it's only a hope!) that the crystal structure will occur. Then the same procedure will be repeated on piperine.

Hope that the crystal structure won't make things difficult to me anymore.

My friend checked for me saying that finally it is my turn to borrow the Geology book. I have long reserved it two or three weeks ago. But when I went to collect it this afternoon at the library, I was told by the librarian that the book is not in my holding list record, which mean that either I did not reserve it, or I have cancelled my reservation.

That is really weird... What has happened? I did not cancel it. And I really DID reserve it. Think that got an intruder secretly cancelled the Geology book reservation in my library account!!!

Sigh... I need to reserve it again and keep on waiting until it is my turn again...
