摘　　要：海风醛是一种醛香型香原料,性质活泼,对光和热敏感,容易分解。通过对海风醛加热后分解产物的GC和GC-MS分析,确证了其分解产物为一氧化碳和1-乙基-4-(2-甲基丙基)苯,并对影响海风醛稳定性的主要因素做了研究。通过研究不同稳定剂对海风醛分解的抑制作用,发现对苯二酚对海风醛分解有很强的抑制作用。通过研究证明,可在实际应用中采取低温、避光和添加适量对苯二酚的方式,有效降低海风醛的分解。Floralozone is a kind of aldehydic fragrance raw material.It is active in nature,sensitive to light and heat,and easy to decompose.The decomposition products of floralozone after heating were analysed by GC and GC-MS.GC and GC-MS analyses of the decomposition products of floralozone,it was confirmed that the decomposition products were carbon monoxide and 1-ethyl-4-(2-methylpropyl)benzene.And the main factors affecting the stability of floralozone were studied.By studying the inhibitory effect of different antioxidants on the decomposition of floralozone,it was found that hydroquinone had a strong inhibitory effect on the decomposition of floralozone.It is proved that the decomposition of floralozone can be effectively reduced by adopting low temperature,avoiding light and adding appropriate amount of hydroquinone in practical applications.
