季戊四醇四苯甲酸酯

【物理化學特性】

季戊四醇四苯甲酸酯,又稱四苯甲酸季戊四醇酯、苯甲酸季戊四醇酯;

英文名pentaerythritol tetrabenzoate;2,2-bis((benzoyloxy)methyl)-1,3-propaned;

分子式:C33H28O8

相對分子質量:552.58

CAS號:4196-86-5

季戊四醇四苯甲酸酯是白色固體狀物,相對密度1.280l(25℃時),熔點97~100℃,折光率1.5715。微溶于水,溶解度<0.1g/100ml(19℃);難溶于脂肪烴和芳香烴溶劑;溶于熱的甲醇和乙醇,冷卻即結晶。

【用途】

季戊四醇四苯甲酸酯是一種非鄰苯類固體增塑劑,作為PVC的加工助劑,代替ACR(丙烯酸酯類改性劑),提高單位產量,顯著降低成本;作為PVC(聚氯乙烯)的固體增塑劑,性能全面還可作為加工助劑,改善壓延纏卷性以及獲得更好的熱穩定性;作為一種性能優良的高溫有機溶劑及高分子材料的添加劑,廣泛地用作增塑劑、塑模脫模劑、電子材料表面涂層抗靜電劑,電子材料的助焊劑、熱溶噴墨的粘合劑以及液晶材料的輔助劑等。由于其優異的熱穩定性,對于PC、PET、PBT、PC合金、PPO、 PPS及其它的熱塑性工程塑料的擠出和注塑都有很好的潤滑效果,在PC、PET、PBT、PC/ABS、PPS色母粒中使用有極好的分散效果。
