摘要
Abstract
A domestic tetrahydrothiophene odorant A and an imported tetrahydrothiophene odorant B were selected for single sample and mixed sample physico-chemical tests.The single sample physicochemical test results show that the purity of both odorants is greater than 99％,and no moisture or insoluble substances are detected.The physicochemical test results of the mixed samples show that the purity of the mixed samples is greater than 99％,and the physicochemical properties of the mixed samples are stable.The odor intensity test of 5 sample gases(the mass concentration of odorant are 1.67,0.50,0.17,0.08,0.05 mg/m3)is carried out.When the mass concentration of odorant is 0.08 mg/m3,the odor intensity of each sample gas can reach level 2 or above in terms of olfactory grade.A public survey is conducted on 5 sample gases(the mass concentration of odorant is both 0.08 mg/m3),and the number of people with odor intensity olfactory grade reaching grade 2 or above in mixed samples is counted.The mixed sample with a volume ratio of 3∶1 between imported tetrahydro-thiophene odorant and domestic tetrahydrothiophene odorant has the highest number of people,accounting for 90.0％of the total number of people.Weighted cal-culation is performed on the results of the K-value ex-periment and the public survey.The weighted result of the mixed sample with a volume ratio of 1∶3 between imported tetrahydrothiophene odorant and domestic tet-rahydrothiophene odorant is the highest.Mixing in a ra-tio of 1∶3 yields better results.关键词
