Wstm of an excess of NaOCH 3 in methanol permits release and titration of this combined water, after approximate neutralization of excess base with acetic acid see Note 9. This combined water is not titrated.

By proper choice of the sample size, KF reagent concentration and apparatus, this test method is suitable for measurement of water over a wide concentration range, that is, parts per million to pure water. When using pyridine-free reagents, commercially available buffer solutions can be added to the sample prior to titration.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Water content, acidity pHhigher heating value HHV and oxygen content of the bio-oil varied between Active view current version of standard Translated Standard: Hydrocarbons saturated and unsaturated.

ASTM E – 01 Standard Test Method for Water Using Volumetric Karl Fischer Titration

Scientific Research An Academic Publisher. Ketones, stable Note 4. Specific warnings are given in 3. Formaldehyde polymers contain water as methylol groups. This test method is designed for use asrm automatic titration systems capable of determining the KF titration end point amperometrically; however, a manual titration method for determining the end point visually is included as Appendix X1.

Oil palm residues represent good source of renewable e023 when all the pyrolysis products are efficiently utilized. Further discussion of interferences is included in Section 5 and Appendix X2.

ASTM E – 16 Standard Test Method for Water Using Volumetric Karl Fischer Titration

Specific warnings are given in 3. By proper choice of the sample size, KF reagent concentration and apparatus, this test method is suitable for measurement of water over a wide concentration range, that is, parts per million to pure water. Amines, weak Note 3.

Pyrolysis products bio-oil, bio-char and non-condensable gas were characterized.

This may be used as solid biofuel, adsorbent and source of carbon. Historical Version s – view previous versions of standard. Low pH, highwater and oxygen contents in the oil make it unsuitable for being used as fuel and therefore require upgrading. Compounds subject to oxidation-reduction reactions in an iodine-iodide system interfere.

Samples that are gaseous at room temperature are not covered see Appendix X4. A Case Study of Zimbabwe from to Some acids, such as formic, acetic, and adipic acid, are slowly esterified.

Among the renewable energy sources, biomass is the only source that has carbon in its building blocks which can be processed to liquid fuel. Referenced Documents purchase separately The documents listed below are referenced within the subject standard asym are not provided as part of the standard.

Examples of stable ketones are diisopropyl ketone, camphor, benzophenone, benzil, dibenzolacetone, etc.

ASTM E203 – 16

Historical Version s – view previous versions of standard Translated Version s: Examples of stable aldehydes are formaldehyde, sugars, chloral, etc. Determination of water using KF coulometric titration is not discussed. Samples that are gaseous at room temperature are not covered see Appendix X4. Searching for alternative energy sources continues to grow in recent times due to the fear of energy insecurity asstm the near future and environmental and sociopolitical issues associated with the use of fossil fuel.

This test method covers the use of both pyridine and pyridine-free KF reagents for determining water by the volumetric titration. Determination of Water Content of Polyols. Acid oxides Note 6. Salts of organic and inorganic acids Note 6. Active view current version of standard. Aldehydes, stable Note 2. Scanning electron microscopy and ultimate analysis axtm the bio-char suggests that it is a porous material and consists mainly carbon between With formic acid, it may be necessary to use methanol-free solvents and titrants 1.
