| 1. | Propylene, butylenes and various other hydrocarbons are usually also present in small concentrations.
|
| 2. | HF acid plants can process a wider range of feedstocks with propylenes and butylenes.
|
| 3. | Unlike the three other types of plastic pipe PB, or poly-butylene, is flexible.
|
| 4. | The yeasts also help keep levels low by consuming diacetyl and reducing it to acetoin and butylene glycol.
|
| 5. | For example, isooctane results from combining butylene with isobutane and has an octane rating of 100 by definition.
|
| 6. | It is a four-carbon branched alkene ( olefin ), one of the four isomers of butylene.
|
| 7. | PBAT has been proven to be fully biodegradable when composted, due to the containment of butylene adiapte groups.
|
| 8. | The production ceased only after the World War II, because it could not compete with butylene-based technologies.
|
| 9. | The train was carrying ethyl methylketone, butylene and phenol carbolic acid, said Terry Durborow, emergency management director in Miami.
|
| 10. | This led to identifying Poly ( butylene adipate-co-terephthalate ) ( PBAT ) as a potential copolymer for blending.
