What is the detection method and standard required value of the boiling range of ethylene glycol for industrial use?

What is the detection method and standard required value of the boiling range of ethylene glycol for industrial use? Diethylene glycol, also known as diethylene glycol, is mainly used as a gas dehydration agent and an aromatic hydrocarbon extraction solvent
.
It is also used as a solvent for nitrocellulose, resin, grease, printing ink, etc.
, as a softener and finishing agent for textiles, and for extracting coumarone and indestigra from coal tar
.
According to the standard requirements of SH/T1056 industrial diethyl glycol, the temperature required for the initial distillation point of the excellent grade in the boiling range of industrial diethyl glycol is greater than or equal to 242 degrees, and the dry point requirement is less than or equal to 250 degrees
.
In accordance with the above standard technical requirements, the boiling range detection method of industrial diethyl glycol adopts the standard requirements of SH/T1053 to detect, and the special instrument for detecting the boiling range of the automatic distillation range instrument SH6536 is fully in line with the standard of SH/T1053, which can automatically detect the initial distillation point and dry point of industrial diethy glycol, automatically determine the automatic results, and automatically print
.
In addition, diethylene glycol is also used as a brake oil compound, celluloid softener, antifreeze and thinner for emulsion polymerization
.
Also used in rubber and resin plasticizers; Polyester resin; Fiberglass; Carbamate foam; Production
of products such as lubricant viscosity improvers.
