浩瀚色譜(山東)應(yīng)用技術(shù)開(kāi)發(fā)有限公司研究了季戊四醇的氣相色譜分離條件和一季戊四醇的定量方法,測(cè)定了一季戊四醇標(biāo)準(zhǔn)樣品的純度,采用外標(biāo)法峰高定量,測(cè)定了商品季戊四醇中一季戊四醇含量.相對(duì)標(biāo)準(zhǔn)偏差小于1%。
GB/T 7815-2008 工業(yè)用季戊四醇
GB/T 7815-2008 工業(yè)用季戊四醇
本標(biāo)準(zhǔn)代替GB/T 7815-1995 工業(yè)用季戊四醇
本標(biāo)準(zhǔn)規(guī)定了工業(yè)用季戊四醇的要求、試驗(yàn)方法、檢驗(yàn)規(guī)則以及標(biāo)志、包裝、運(yùn)輸和貯存等。
本標(biāo)準(zhǔn)適用于以甲醛和乙醛為原料,氫氧化鈉或氫氧化鈣為催化劑生產(chǎn)的工業(yè)用季戊四醇的生產(chǎn)、檢驗(yàn)和銷售。

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has studied the gas chromatography separation conditions of pentaerythritol and the quantitative method of pentaerythritol. The purity of the standard sample of pentaerythritol was determined, and the peak height quantitative method was used to determine the content of pentaerythritol in commercial pentaerythritol. The relative standard deviation was less than 1%.
GB/T 7815-2008 Pentaerythritol for Industrial Use
GB/T 7815-2008 Pentaerythritol for Industrial Use
This standard replaces GB/T 7815-1995 pentaerythritol for industrial use
This standard specifies the requirements, test methods, inspection rules, marking, packaging, transportation, and storage of industrial pentaerythritol.
This standard applies to the production, inspection, and sales of industrial pentaerythritol using formaldehyde and acetaldehyde as raw materials and sodium hydroxide or calcium hydroxide as catalysts.
