Popis
BS 506-2:1984
This standard BS 506-2:1984 Methanol for industrial use is classified in these ICS categories:
- 71.080.60 Alcohols. Ethers
This British Standard gives general instructions and describes methods of test for the analysis of methanol for industrial use.
The methods of test relating to methanol for industrial use are the following:
- Determination of density at 20 °C
- Determination of residue on evaporation on a water bath
- Measurement of colour
- Determination of distillation range
- Determination of water content
- Detection of the alkalinity or determination of the acidity to phenolphthalein
- Estimation of content of carbonyl compounds present in small amounts – Spectrometric method
- Estimation of content of carbonyl compounds present in moderate amounts – Titrimetric method
- Test for miscibility with water
- Determination of permanganate time
- Determination of sulphur compounds
Gives instructions for sampling and test reports, and methods for distillation range, alkalinity or acidity to phenolphthalein, carbonyl compounds, miscibility with water, permanganate time and sulphur compounds. Also gives cross-references to relevant general methods.
