Application

Cyrene在某些应用中可取代NMP和/或DMF，比如对于石墨烯溶液而言，Cyrene由于适宜的极性和高粘度，可以制备较大且缺陷较少的石墨烯薄片，分散能力超过NMP。下为Cyrene™的更多用途。

1.石墨烯溶液分散。
2.替代DMF用于金属有机骨架合成。
3.有机合成：

Features and Benefits

  • 28天内降解99%
  • 焚烧稳定
  • 无致突变性和基因毒性
  • ASTM D6866——测定生物质含量的标准方法
  • 由可再生资源−纤维素制备而成

General description

我们致力于为您带来更加绿色的替代产品，这些产品遵守一项或多项绿色化学12项原则。该产品是可生物再生的，因此符合"设计更安全的化学品"， ″更安全的溶剂和助剂″以及″使用可再生原料″的原则。点击 此处 以获取更多信息。

Cyrene是生物基双极性分子，生命周期终止处理后，安全降解成为CO2和H2O。可作为非质子类溶剂取代存在环境问题的普通溶剂。REACH将许多溶剂归为SVHC高度关注物质，其中包括N-甲基吡咯烷酮(NMP)和N,N-二甲基甲酰胺(DMF)，Cyrene™正是这些溶剂的替代品。

  1. What is a BioRenewable solvent?

    BioRenewable solvents are sourced from renewable and sustainable biobased materials, such as soy/palm oil, wood waste, hay or corn byproducts, etc. It is important to highlight that our BioRenewable products do not compete with food production.

  2. Why should you use BioRenewable solvents?

    You will contribute to create a sustainable world, significantly lowering environmental impact. Biorenewable solvents also decrease petroleum sources dependency, have higher recovery rates, and/or are safer for handling and disposal.

  3. Do BioRenewable solvents have a similar quality to petroleum-based solvents?

    BioRenewable solvents can have the same or higher purity level compared to traditional solvents. These solvents are free of the many byproducts of petroleum manufacturing, such as benzene, aldehydes, and ethers.
