    癸二酸二辛酯 (DOS)

    癸二酸二辛酯 (DOS) – Bio-Based Specialties product from Bio Green Oleo

    关于此产品

    癸二酸二辛酯,规范名称为癸二酸双(2-乙基己基)酯,是癸二酸与 2-乙基己醇形成的双酯。从油脂化学角度看,其价值在于酸组分:癸二酸是少数真正生物基且具有商业重要性的二元酸之一,由蓖麻油中的蓖麻油酸经碱裂解制得。

    这一来源使分子在两个酯基之间具有一条长而柔性、完全饱和的脂肪链,其性能也由此直接决定。不含芳环使倾点极低、粘度指数很高,而酯键则赋予良好的热稳定性、氧化安定性和金属润湿性。

    这正是合成润滑油所需要的性能。此类双酯基础油早已广泛应用于航空涡轮机油、压缩机油和高性能润滑脂中,在这些应用中其适用温度范围比矿物油更宽。同样的低温柔韧性使其成为聚合物配方中有价值的耐寒增塑剂。

    供应取决于蓖麻油和癸二酸的可得性,而其产区高度集中,因此请在询价时确认产地和当前规格。
