What is the evaporation rate of butyl acetate?
1.0
Eastman™ Butyl Acetate has an evaporation rate of 1.0, which provides a quick drying lacquer without inducing blushing under normal circumstances. It is a urethane grade solvent and is widely used in 2-K polyurethane coatings to help balance flow and dry time.
Does butyl acetate evaporate?
The evaporation rate can be useful in evaluating the health and fire hazards of a material. The designated standard material is usually normal butyl acetate (NBUAC or n-BuAc), with a vaporization rate designated as 1.0.
How do you calculate evaporation rate?
This reflects the volume of liquid that has evaporated. For example, 500 mL – 495 mL = 5 mL. Divide the volume of liquid that evaporated by the amount of time it took to evaporate. In this case, 5 mL evaporated in an hour: 5 mL/hour.
Is evaporation rate on SDS?
SDS Relevance Evaporation rates generally have an inverse relationship to boiling points; i.e. the higher the boiling point, the lower the rate of evaporation. The general reference material for evaporation rates is n-butyl acetate (commonly abbreviated BuAc) which has the chemical structure shown below.
Does acetone fully evaporate?
Acetone does not participate in hydrogen bonding, so its intermolecular forces are comparatively weaker, and it evaporates most quickly.
What is the evaporation point of acetone?
Enthalpy of vaporization
| Temperature (K) | 300. – 345. |
|---|---|
| A (kJ/mol) | 46.95 |
| β | 0.2826 |
| Tc (K) | 508.2 |

Does hexane evaporate quickly?
Hexane reached a lower minimum temperature than heptane. This means that hexane evaporated more quickly than heptane.
How long does it take acetone to dissipate?
Acetone evaporates rapidly, even from water and soil. Once in the atmosphere, it has a 22-day half-life and is degraded by UV light via photolysis (primarily into methane and ethane.) Consumption by microorganisms contributes to the dissipation of acetone in soil, animals, or waterways.
Does acetone evaporate at room temp?
At room temperature the rate of evaporation of acetone is slow, to speed up the process to evaporate all the acetone in the mixture, we supply heat.
What is the average evaporation rate of water?
Average Evaporation On average a water feature will lose ½% to 1% of the gallons pumped per hour in a day. Remember to use the actual gallons pumped per hour, not just the size of the pump.
