1, start date. (upper left corner of experimental report)
Date of completion. (The lower left corner of the experimental report)
2. Batch number of the experiment. You don't have to press this number. Li Li commented.
Li Li commented: Numbers don't have to be based on this.
3. The number of pages in the experimental notebook is 00 1 ~ 030. (upper right corner of experimental report)
4. Theoretical output (upper right corner of experimental report)
5. Complete chemical reaction equation.
The code, molecular formula and molecular weight of initiator/product shall be indicated.
6. Referee.
Please indicate the literature source or patent number when citing patents, and the experimental batch number when citing experiments by other researchers.
7. Materials.
(1) The name, molar number and equivalent number (eq) of each reagent shall be recorded in detail.
Weight (g), volume (ml), density (d), etc.
If the reagents used are made by yourself or colleagues, please indicate the source.
For example, please indicate that it comes from this 001-hy-0102-b.
Please indicate that it is from Ben 001-zzh-0102-c for colleagues to make.
8. Procedures.
(1) The experimental contents should be recorded in detail, including reaction settings, materials and quantity, feeding sequence (feeding mode), color change, exothermic phenomenon, reaction operation time, reaction operation mode, sampling method, analysis method, yield, weight, purity, etc.
(2) If abnormal phenomena or results are found in repeated experiments, it is necessary to point out the abnormal points as far as possible and explain the reasons; If subsequent experiments can prove the cause of the abnormal phenomenon, the verification results must be added to this experimental report.
(3) the dosage of each chemical used, if the reagent used is self-made acid or alkali, etc. Please calculate the original consumption and indicate it on the side so as to register the raw material consumption record.
For example, if 40ml of 1N HCl is used, please calculate the amount of concentrated hydrochloric acid.
Then 40ml×1n = 3.33ml×12n,
When vacuum distillation is carried out, the type of pump (water pump, oil pump), tank temperature, internal temperature and vacuum degree should be indicated.
4 sampling method (example)
5 analysis method. (example)
If the reaction is detected by TLC, all "meaningful" TLC films must be drawn in real size.
Check the blank space on the right side of the record book without horizontal lines for future comparison.
7 file name. (file name)
For a complete chemical reaction, there should be a systematic naming method from raw materials to crude products, pure products and final products obtained after the reaction, so that the data atlas obtained by GC, NMR or HPLC can be stored in the hard disk of the computer, and if it needs to be retrieved or viewed later, the state of the atlas can be clearly determined.
9. Experimental results: product characteristics (appearance), weight, yield, purity, optical purity and so on.
10, discussion: important conclusions of this experiment, discussion of problems, measures for the next experiment, etc.
10, signature.
After each experiment, please sign and date in the lower right corner of the experiment record book. If more than two people (including) participate in the project, each person needs to sign.
Special instructions:
1, the experimental notebook must record the progress in time, truly and objectively, and truly record what the experimental results are; Where the experiment is done, it is written there. "You can't have preconceived ideas, let alone have your own subjective imagination.
Don't leave the laboratory unless absolutely necessary. If it is necessary to leave the laboratory under special circumstances, it must be approved by the department head.
3. Experimental records can be written in Chinese or English.
4. After the completion of the project, the experimental records must be reviewed by the department head and submitted to the R&D department for centralized filing management.
