We remind you: this is just some common test methods, na verdade, for ethylene glycol monobutyl ether performance test may have other parameters and test methods.
Método de detecção
The following is a detailed description of the detection method for the performance parameters of ethylene glycol monobutyl ether:
Densidade relativa: Put the sample of ethylene glycol single butyl ether in a specific gravity bottle of known weight, measure the total mass of the mixed liquid of ethylene glycol single butyl ether and water in the specific gravity bottle, and then measure the mass of water filled in the specific gravity bottle. The relative density can be calculated by the total mass and the mass of water.
Índice de refração: The refractive index of ethylene glycol monobutyl ether is calculated by dropping the sample of ethylene glycol monobutyl ether into a solution with known refractive index and measuring the degree of light refraction in the sample using a refractometer.
Melting point and boiling point: Using a melting point meter or boiling point meter, the melting point and boiling point of ethylene glycol monobutyl ether are measured at standard atmospheric pressure.

Water content: Using the Karl Fisher method, the water in ethylene glycol monobutyl ether is converted into carbon dioxide and water by catalytic reaction, and then the mass of carbon dioxide after reaction is measured by electronic balance, so as to calculate the water content in ethylene glycol monobutyl ether.
Valor ácido: Using acid-base titration, the acid value of ethylene glycol monobutyl ether was calculated by dropping a sample of ethylene glycol monobutyl ether into a known concentration of alkali solution until a neutral point appeared in the solution and recording the required amount of drops.
Solubilidade: The solubility of ethylene glycol monbutyl ether was assessed by mixing and stirring the sample with various solvents to observe whether ethylene glycol monbutyl ether could be dissolved in the solvent.
Stability: The sample of ethylene glycol monobutyl ether is exposed to different environmental conditions, such as high temperature, high humidity, sun exposure, etc., to observe whether the ethylene glycol monobutyl ether changes, and the corresponding chemical analysis is carried out to evaluate the stability and degradation performance of ethylene glycol monobutyl ether.
Nós lembramos você: different performance parameters may require different test equipment and methods, and some tests may require professional laboratories or professional technicians to complete. Ao mesmo tempo, for some performance parameters, it is also necessary to follow the relevant standards and specifications, such as ASTM (Sociedade Americana de Testes e Materiais) ou ISO (Organização Internacional para Padronização), etc., to ensure the accuracy and reliability of the test. Além disso, different countries or regions may have different performance testing methods for ethylene glycol monobutyl ether, and specific testing methods should refer to local standards and regulations.
