    • Provided are processes for making, and processes for using triglycerides as plasticizers. Mixed triglyceride plasticizers can be produced by recovery of linear or branched C4 to C13 aldehydes from a hydroformylation product, oxidation to the acid with oxygen and/or air, recovery of the resulting acid, and esterification with a crude glycerol, wherein the total carbon number of the triester groups is from 20 to 25 for greater than or equal to 45 wt % of the plasticizer. The product selectivity obtained from esterifying with crude glycerol is comparable to that of esterifying with pure glycerol. Such plasticizers can be phthalate-free and provide outstanding properties including a suitable melting or glass transition or pour point, low volatility, increased compatibility, and excellent low temperature properties in a range of polymeric resins.
    • 提供了制备方法和使用甘油三酯作为增塑剂的方法。 混合甘油三酯增塑剂可以通过从加氢甲酰化产物中回收线性或分支的C 4至C 13醛,用氧气和/或空气氧化成酸,回收所得酸,并用粗甘油进行酯化来制备,其中总碳数 的三聚物组合物的增塑剂的含量为大于或等于45wt%的20至25。 用粗甘油酯化获得的产物选择性与用纯甘油酯化的产物选择性相当。 这种增塑剂可以是无邻苯二甲酸酯,并提供突出的性能,包括合适的熔融或玻璃化转变或倾点,低挥发性,增加的相容性和在一系列聚合物树脂中的优异的低温性能。
