名稱:毛細(xì)管柱
固定液:聚乙二醇
規(guī)格:30m*0.32mm*0.25um

應(yīng)用:GB/T 14190-2017 纖維級(jí)聚酯(PET)切片試驗(yàn)方法
聚對(duì)苯二甲酸乙二酯(PET)的生產(chǎn),不論是采用對(duì)苯二甲酸二甲酯(DMT)和乙二醇(EG)的酯交換法或是高純度的對(duì)苯二甲酸(TPA)和乙二醇的直接酯化法,特別是直接酯化法,由于反應(yīng)過(guò)程中副反應(yīng)產(chǎn)生的二甘醇(DEG)以類似于乙二醇的方式而進(jìn)入聚酯 。
浩瀚色譜(山東)應(yīng)用技術(shù)開發(fā)有限公司采用氣相色譜儀測(cè)定聚酯中的二甘醇含量,探討了不同色譜參數(shù)對(duì)測(cè)試數(shù)據(jù)的影響,為采用該方法測(cè)定二甘醇含量的生產(chǎn)或研究工作提供了借鑒與指導(dǎo)。

Diethylene glycol in fiber grade polyester (PET) chips GB/T 14190-2017 Details:
Name: capillary column
Fixative: polyethylene glycol
Specifications: 30m*0.32mm*0.25um
Model: PEG-20M
Application: GB/T 14190-2017 Fiber Grade Polyester (PET) Chip Test Method
Production of polyethylene terephthalate (PET), either by transesterification of dimethyl terephthalate (DMT) and ethylene glycol (EG) or high-purity terephthalic acid (TPA) In the direct esterification method with ethylene glycol, especially the direct esterification method, the diethylene glycol (DEG) produced by the side reaction during the reaction enters the polyester in a manner similar to that of ethylene glycol.
