Most compounds a research program needs already exist. A catalog search finds them, a purchase order goes out, and the material arrives within a few days. That covers the majority of routine laboratory and formulation chemistry. What it does not cover is the compound your program specifically needs that does not exist yet — or […]
The piperazine anhydrous bottle has been on the bench for three months. It was resealed after each use. The visible appearance is unchanged white crystalline powder, no obvious clumping. The yield on this step has dropped from 82% to 71% across the last four batches, and nobody can explain it. The most likely explanation is […]
In polyolefin process development, 1-pentene is rarely the first alpha-olefin that comes to mind. 1-Butene, 1-hexene, and 1-octene dominate the commercial LLDPE comonomer conversation. But 1-pentene occupies an important position in catalyst research and specialty resin production and its behavior in Ziegler-Natta versus metallocene systems illustrates, more clearly than most other comonomers, why catalyst architecture […]
