A test substance with characteristics and properties similar to those of cellulose-based solid waste products is needed to calibrate calorimeters and combustors which will be routinely burning these materials to determine their calorific values precisely for use in commerce. Microcrystalline cellulose was found to be a good calibrant for this purpose. The enthalpy of combustion of microcrystalline cellulose at (25 °C), and its estimated uncertainty, was determined to be -2812.401±1.725 kJ/mol based upon the sample mass. A calculated heat of wetting correction of 1.514 kJ/mol was applied to the combustion data.
需要一种特性和性质与纤维素基固体废物产品相似的测试物质来校准量热计和燃烧器，这些仪器将常规燃烧这些材料以精确测定其热值，供商业使用。发现微晶纤维素是用于此目的的良好校准物。基于样品质量，微晶纤维素在（25°C）下的燃烧焓及其估计的不确定度被确定为-2812.401±1.725 kJ/mol。对燃烧数据应用了计算得出的1.514 kJ/mol的润湿热校正。
