腰果壳液(CNSL)

关于此产品
腰果壳液(通常缩写为 CNSL)提取自腰果(Anacardium occidentale)果壳内部的海绵状蜂窝层。其 CAS 号为 8007-24-7,以深棕色黏稠液体供应,气味刺鼻。由于取自果壳而非果仁,它是腰果加工的真正副产品,而非为化工用途专门种植的作物。
商业上有两种形态,二者不可互换。天然(冷榨)CNSL 以腰果酸为主,通常约占 70%,另含腰果二酚和较少的腰果酚。工业级 CNSL 通过焙烧果壳制得,焙烧使腰果酸脱羧生成腰果酚,因此工业级富含腰果酚。上述组分均为带有十五个碳原子不饱和侧链的烷基酚,而这条侧链正是 CNSL 价值所在:它使衍生树脂天然具备石油基苯酚树脂所不具备的柔韧性和耐热性。该液体在未加工状态下因酚类含量而具有皮肤刺激性,须采取适当的操作防护。
用于生产腰果酚和 CNSL 基酚醛树脂、制动器与离合器摩擦材料、铸造型芯粘结剂、表面涂料、环氧固化剂、层压板及特种中间体。
Bio Green Oleo 按腰果酸与腰果酚含量、黏度、水分、灰分和碘值的规格供应天然级与工业级 CNSL。
