Lab notebook experiment page template
Free template. Download it, or open it in MolDraw to change it first.
A filled notebook page for the Fischer esterification of 4-aminobenzoic acid to benzocaine: header fields, reaction scheme, a reagent table (MW, equiv, mmol, mass/volume, density, lot) worked from the limiting reagent, procedure, observations, a TLC sketch, yield calculation and characterisation fields.
What the template shows
- One experiment per page: plan it, run it, record it, work out the yield
- Notebook / page:
- local anaesthetics
- Expt code:
- Fischer esterification of 1 (10 mmol scale)
- Ref. / precedent:
- Reaction scheme and reagent table
- 4-aminobenzoic acid (1)
- ethyl 4-aminobenzoate (2)
- mass / vol
- supplier / lot
- 4-Aminobenzoic acid (1)
- Ethanol, absolute
- dry · lot ______
- Ethyl 4-aminobenzoate (2) (theor.)
- mmol = mass / MW, or volume × density × purity / MW; equiv relative to 1 (limiting, 9.99 mmol). Ethanol is the solvent and is in large excess.
- Observations (time · note)
- 10:05 white suspension; H₂SO₄ added, solid clumps then dissolves
- 10:20 reflux begins, clear pale solution
- 12:20 TLC: 1 consumed (see sketch)
- 12:45 Na₂CO₃: CO₂ evolution, white precipitate
- TLC sketch
- hexane/EtOAc 2:1, UV 254 nm · Rf 1 0.10, 2 0.45, X (trace) 0.70
- Limiting reagent: 1, 9.99 mmol

Frequently asked questions
Is the Lab notebook experiment page template free?
Yes. The Lab notebook experiment page template is one of the free MolDraw templates: open it in the editor or download it from this page as SVG or PNG and use it in your slides, worksheets and notes.
Can I edit the Lab notebook experiment page template?
Yes. It opens as an ordinary MolDraw drawing, so every structure, arrow, label and colour can be changed, and you can add your own content around it.
Is the chemistry checked?
Every structure is checked with RDKit and every curly arrow passes MolDraw’s electron-flow audit. The sources used are listed on this page.
What goes on the lab notebook experiment page?
The reaction scheme, a reagent table with amounts and equivalents, the procedure, observations, yield and characterisation, in the order most notebooks require.
