Silver Chain is firstly taken as research object for the analyses of induced discoloration; the paper carried on content determination of extractives of Silver Chain, analyzed the color different and the vision physics parameters before and after discoloring under different pretreatment conditions, and, took the samples for chromatographic analysis by infrared spectrum and GC-MS. The results showed: (1)The color of Silver Chain tended to be dark and uniform gray-brown; (2)Under the condition in high temperature steaming, the color of Silver Chain was much more uniform; (3)The preliminary conclusion of the effect of extractives in induced discoloration was:①After induced discoloration,The carbonyl (-C=O) and the conjugated double bond(C=C)increase, belong to chromophoric groups, which made the wood color deeper;②There were plenty of auxochromic groups and chromophoric groups in the acetone extractives of silver chain, the interaction between the auxochromic groups and the chromophoric groups makes the wood color deeper.
研究結果表明:(1)刺槐顏色的變化趨勢向深色方向變化,可獲得均勻的深褐色;(2)高溫汽蒸條件下,處理后木材顏色更加均勻;(3)初步得出抽出物對誘發(fā)變色的作用為:①經誘發(fā)變色處理后的刺槐丙酮抽出物中,含有羰基-C=O等發(fā)色基團的物質濃度有所升高,與芳環(huán)共軛的C=C也有所增加,促使了刺槐顏色加深;②刺槐木材丙酮抽出物的主要成分中含有大量發(fā)色基團和助色基團,這些基團間的相互作用使木材顏色加深。
