How to Buy Acryloylmorpholine (ACMO)
Acryloylmorpholine (ACMO, CAS 5117-12-4) is a reactive monomer, so buying it well means fixing the purity, colour, viscosity and inhibitor level – and handling a reactive liquid correctly. This page sets out what to confirm before you request a quotation.
1. Fix the specification
| Parameter | Specification |
|---|---|
| Purity (content) | 98% min |
| Colour | 50 APHA max |
| Viscosity (25 °C) | 9 – 15 mPa·s |
| Inhibitor (additive) | 1000 ± 100 ppm |
| Density | 1.118 – 1.122 g/cm3 |
| Flash point | 126.5 °C |
| Boiling point | 158 °C |
| Melting point | -8 °C |
| Hygroscopicity | 1.8 g/100 g (at 20 °C, 60% RH) |
For UV coating/ink use, the colour (50 APHA max) and inhibitor level (1000 ± 100 ppm) are the parameters to watch; the low colour keeps films bright, and the inhibitor keeps the monomer stable.
2. Grades and packaging
| Item | Standard |
|---|---|
| Grade | Technical monomer, 98% min |
| Packaging | 200 kg drums or IBCs (or as agreed) |
| Documentation | Per-batch COA and SDS |
3. Storage and shelf life
- Keep sealed, cool and dark – it is a reactive monomer and moderately hygroscopic.
- Preserve the inhibitor – do not strip it; check the drum is closed to keep the inhibitor level and limit moisture pickup.
- Avoid heat, light and initiators – these can trigger premature polymerisation.
- Respect shelf life – buy in line with consumption, especially in warm climates.
4. What drives the price
ACMO price tracks the morpholine and acrylic (acid/ester) feedstock, plus the cost of stabilisation and purification. Committed tonnage gives the best terms.
5. A short enquiry checklist
- Product and CAS 5117-12-4; grade (technical monomer).
- Specification (purity, colour, viscosity, inhibitor level).
- Packaging (drums / IBCs) and delivery port.
- Tonnage and Incoterm (FOB / CIF).
- Documents (COA, SDS).
Frequently Asked Questions
What should I check first when buying ACMO?
The colour and the inhibitor level – both are critical for a radiation-cure monomer, and both are on the specification.
Why does ACMO contain an inhibitor?
Because it is a reactive monomer; about 1000 ± 100 ppm of inhibitor prevents premature polymerisation in storage.
How is ACMO packed?
200 kg drums or IBCs (or as agreed).
Does it need special storage?
Yes – sealed, cool and dark, away from heat, light and initiators, and within its shelf life.
Do you provide a COA per batch?
Yes – a certificate of analysis for each batch, plus an SDS.
