脱羧腰果壳液(DCNSL)

关于此产品
脱羧腰果壳液以 DCNSL 供应,也称技术级腰果壳液,由天然腰果壳液加热制得,加热过程中其所含腰果酸脱去二氧化碳并转化为腰果酚。它是深棕色黏稠液体,也是腰果壳液进入工业应用的主要形态。
这一变化不仅仅是酸度下降。腰果酸的羧基直接连接在芳环上,该基团热稳定性差:在树脂固化过程中会分解并释放二氧化碳,导致发泡、空隙和结果不稳定。事先将其除去,可得到在高加工温度下性能可预测的原料。剩余组分化学结构更简单,并且在树脂化学师所需的意义上反应性更强,其主要成分为腰果酚——一种带有十五碳不饱和侧链的酚。该侧链相当于内置增塑剂,因此以 DCNSL 制得的树脂比石油基酚制得的树脂更坚韧、脆性更低,残余不饱和键还提供了额外的交联点。
该产品用于刹车片、离合器面片等摩擦材料,酚醛树脂和环氧树脂体系,铸造粘结剂,涂料,胶粘剂,层压板,以及作为蒸馏腰果酚的原料。
Bio Green Oleo 按腰果酚含量、残余腰果酸、黏度、水分、灰分和碘值等规格供应 DCNSL。
