γ-BHC在黑暗、紫外光和日光下的异构化

Isomerization of y-BHC in the Dark and under the UV &the Sunlight

γ-BHC在黑暗、紫外光和日光下都能迅速地消失.紫外光照射下消失得最快,日光下次之,黑暗下较慢.黑暗下未检出γ-BHC的异构化产物.紫外光和日光均能促进γ-BHC的异构化.异构化的主要产物为α、δ-BHC,它们的异构化率在0.04%～0.17%之间.

γ-BHC disappears in the dark, under the UV and the sunlight. The disappearance of γ-BHC under the exposition to the UV is faster than to the sunlight, but it is slower in the dark. The isomerization products haven't been detected in the dark, but the UV and the sunlight can accelerate the isomerization of γ-BHC.The isomerization products of γ-BHC are α-BHC and δ-BHC, The isomerization ratio is between 0.04%-0.17%.
