Dear Customer:

The current international situation is complex and volatile, and uncertain tariff policies may potentially impact our product prices. Given these uncertainties, we value your understanding regarding order-related matters.

If you decide to place an order during this period, we reserve the right to adjust the price based on the evolving situation. We understand that market changes may cause inconvenience. We will negotiate with you if there’s a significant price fluctuation due to tariff policy changes before the order’s actual delivery, and in such cases we may adjust or cancel the order as necessary.

一般描述

我们竭诚为您带来符合一项或多项绿色化学12项原则要求的绿色替代产品。庚烷是比己烷更环保的溶剂,因此符合“更安全的溶剂和助剂”原则。点击此处以获取更多信息。

应用

庚烷可以作为溶剂用于化学中间体的色谱纯化。它也可用作在离子液体存在下萃取芳香族硫化合物的萃取溶剂。庚烷被用作己烷的替代溶剂,用于从棉籽中提取油,因为它不像己烷那样具有环境问题。[1][2][3]
