Plan a trial for your application
Esterification feedstock
Calculate the sample charge from actual acid assay. Correct for water introduced and record differences at the reaction endpoint.
Color-sensitive synthesis
Compare acid color, iron and evaporation residue. Keep finished-product appearance samples for comparison.
Purchase specifications and incoming inspection
Include the intended grade or current specification in the enquiry. Use the table to compare selection criteria and inspection conditions. The specification agreed by both parties defines the contractual limits. ENVO public product information · Verify against the ordered grade and lot ↗
| Property | Unit | Published or agreed specification | Test conditions and checks |
|---|---|---|---|
| Color value | Hazen (Pt-Co) | Set the upper limit for the intended use. | Specify the colour scale and comparison conditions. Record the sample result and contractual maximum separately. |
| Moisture | Mass fraction | Set the upper limit for the synthesis step. | Use the agreed water determination method and record how the sample was sealed. |
| Evaporation residue | Mass fraction | Set the limit from the residue allowance in the finished product. | Specify evaporation temperature, sample mass and the reporting limit of quantification. |
When approving a sample, record the grade, methods, limits and specification revision. On receipt, match the packing lot number to the lot-specific COA and record the measured values and release decision.
Chemical identity
| Database entry | Molecular or composition formula | Molar mass |
|---|---|---|
| Acetic Acid | C2H4O2 | 60.05 g/mol |
The values refer to the compound indicated. Confirm hydrate form, solution concentration and blend composition for the commercial grade.
From samples to commercial delivery
Packaging and receiving
ENVO lists HDPE drums and IBCs. Confirm the acetic acid concentration before agreeing the container, net weight and discharge connection.
Storage and handling
For cold routes, agree the expected physical state and receiving procedure before booking. Check concentration-specific safety information against the shipment SDS.
Sample and order lead times
State the concentration or hydrate, initial net quantity, destination and unloading method. Confirm minimum order, pallet or truckload quantity, dispatch point and arrival date separately.
Questions from the plant
Why do two tonne-based offers deliver different amounts of acetic acid?
Compare delivered cost per unit of active acid. Check container compatibility and the receiving system.
How can we compare colour reports for acids of similar strength?
Use the same colour scale and sample conditions. Confirm the container matches the sample tested and assess the finished product for colour-sensitive uses.
Report a delivery or batch issue
Include the order number, lot number from the package, label photos and inspection records for the affected lot. When retesting, check acetic acid mass fraction, Moisture, Color value.
