Test methods for industrial stearic acids.-.Determination of water content1 Subject content and applicable diagram
This standard specifies the method for the determination of water content in industrial stearic acid. UDC 668. 1. 012bzxz.net
：543.06
GB 9104.6---88
This standard applies to the determination of water content in industrial stearic acid produced by pressing or distillation after hydrolysis of animal and vegetable fats. It is not applicable to fatty acids containing less than dodecanoic acid.
2 Apparatus
2.1 Constant temperature oven.
2.2 Weighing bottle 50mL, low type.
3 Test procedure
Accurately weigh about 10g of sample into a clean weighing bottle with constant weight, put it into a constant temperature oven at 105±1℃, remove the lid of the weighing bottle and dry it for 2h, then cover it, take it out and put it into a desiccator to cool for 30min before weighing. 4 Calculation of results
mo - mi × 100
Where: A—
water acid content, %,
sample mass, g;
mi -sample mass after drying, g.
The allowable error of parallel test results is 0.02%. Additional remarks:
This standard is proposed by the Ministry of Light Industry of the People's Republic of China. This standard is under the technical jurisdiction of the Daily Chemical Industry Science Research Institute of the Ministry of Light Industry. This standard is drafted by the Daily Chemical Industry Science Research Institute of the Ministry of Light Industry. This standard is equivalent to the Japanese Industrial Standard JIS K3331 "Industrial Hardened Oil Fatty Acids" Determination of moisture and volatile matter - oven method.
Approved by the Ministry of Light Industry of the People's Republic of China on April 30, 1988 and implemented on October 1, 1988
