Data

Physical Properties

Typical values for the 99.5% industrial grade, measured on production lots.

Typical values, not for specification.
Property	Limit

Ethanol	≤0.10 wt%
Acidity as acetic acid	≤0.005 wt%
Colour	≤10 Pt-Co
Residue on evaporation	≤5 mg/100 ml
Density at 20 °C	0.898–0.902 g/ml
Distillation range	IBP ≥76.0 °C, dry point ≤78.5 °C

Typical values, not for specification. Sasol publishes a specification for the 99.8% grade (purity min 99.8 wt%, water max 0.03%, ethanol max 0.02%); the values above describe this industrial grade and the certificate of the shipped lot governs.

Fit Check

Grade Fit Checklist

Five questions decide whether 99.5% is enough for the line, or whether the process already needs 99.8%.

01

Moisture-sensitive catalyst

Water at ≤0.10% still consumes isocyanate and metal catalysts. The loss appears as slow cure, not as an off-spec number.
02

Dry point below 78.5 °C

A wider distillation tail lengthens the drying window and can trap solvent in thick films.
03

Appearance-critical coating

Residue at ≤5 mg/100 ml may leave haze or craters on clear coats and print work.
04

Pharmacopoeial documents

99.5% is a market grade; NF, USP or EP documents come only with the pharmacopoeial grades.
05

Long storage after opening

An open drum absorbs moisture; a looser starting limit leaves less room before the limit is reached.

Any answer of yes: step up to 99.8% before the trial runs.

Handling

Handling Notes

Ethyl acetate is a flammable liquid with a flash point near −4 °C. These four points cover the usual failure modes on an industrial line.

Ground before transferBond and ground drums, tanks and lines before transfer.
Keep away from ignitionStore away from heat and ignition sources; keep the drum closed between draws.
Protect a part-used drumBlank with dry nitrogen or finish the drum; moisture pickup starts the day it is opened.
Set the dilution on the benchFix the dilution ratio against the actual resin system, not a generic thinner table.

Applications

Typical Applications

General solvent work where cost per kilo leads and the film is not inspected for residue.

General coatings and thinners Industrial cleaning and degreasing Ink thinning Extraction carrier, non-pharmacopoeial Industrial cleaner formulations

Choose 99.5% for cost-first work where moisture and residue do not reach the finished article. For appearance-critical coatings, polyurethane systems or pharmacopoeial use, take the grade built for those limits instead.
