摘　　要：针对现行国家标准GB/T 23855—2009《液体三氧化硫》在三氧硫质量分数测定过程中将液体三氧化硫产品中的硫酸计为三氧化硫,使得产品中实际的游离三氧化硫的质量分数的计算结果偏高的情况,提出在该标准测试条件下将液体三氧化硫产品中游离三氧化硫和硫酸质量分数分别计算,从而减少计算误差。According to the cun＇ent national standard GB/T 23855-2009 liquid sulphur trioxide in the detennination of sulphur tri- oxide content, the sulphunc acid in the liquid sulphur trioxide product is calculated as sulphur troxide, so that the calculation resuh of the actual free sulphur trioxide content in the product is higher. In this case, a calculation method tor calculating the mass fraction of free sulphur trioxide and sulphuric acid in the liquid sulphur trioxide products under the standard test conditions is proposed.
