Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces LY/T 1182-1995 "β-pinene".
Compared with LY/T 1182-1995, this standard has the following main differences.
--- The color is changed to the platinum-cobalt method, and the color number is revised to 30;
--- Determination of relative density was modified to the densitometer method;
--- β-pinene content calculation does not contain myrcene;
Determination of β-pinene content by capillary column chromatography;
--- Eliminated the product level of β-pinene content of 80% and 90%.
This standard was proposed by the Institute of Chemical Industry of Forest Products of the Chinese Academy of Forestry.
This standard is under the jurisdiction of the Institute of Chemical Industry of Forest Products of the Chinese Academy of Forestry.
This standard was drafted. Institute of Chemical Industry of Forest Products of China Academy of Forestry, Foshan Sanshui Jingze Chemical Co., Ltd., Guangxi
