應(yīng)用：HG/T 4471-2012 工業(yè)用二季戊四醇

二季戊四醇是一種重要的精細(xì)化工產(chǎn)品,與酸酯化后可制成具有良好耐高溫性能的潤(rùn)滑劑,也可用作聚烯烴薄膜的抗霧劑。在采用季戊四醇為原料生產(chǎn)二季戊四醇的過(guò)程中,為了避免副產(chǎn)物的增多,需要控制季戊四醇的轉(zhuǎn)化率不能太高,但同時(shí)又要提高二季戊四醇的回收率,因此必須建立一套快速、準(zhǔn)確的分析方法,及時(shí)對(duì)反應(yīng)液中季戊四醇和二季戊四醇的含量進(jìn)行測(cè)定。

Determination of dipentaerythritol capillary column HH-1
Capillary column HH-1 for the determination of dipentaerythritol Details:

Name: capillary column

Fixative: Dimethicone

Specifications: 25m*0.32mm*0.3um

Model: HH-1

Application: HG/T 4471-2012 Industrial dipentaerythritol



Dipentaerythritol is an important fine chemical product. After esterification, it can be made into a lubricant with good high temperature resistance and can also be used as an antifogging agent for polyolefin films. In the process of using pentaerythritol as raw material to produce dipentaerythritol, in order to avoid the increase of by-products, it is necessary to control the conversion rate of pentaerythritol not to be too high, but at the same time to improve the recovery rate of dipentaerythritol, so it is necessary to establish a set of rapid and accurate analysis method, the contents of pentaerythritol and dipentaerythritol in the reaction solution were determined in time.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. used capillary column HH-1 to determine industrial dipentaerythritol, with high column efficiency, good separation, and satisfactory results.
