Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | 2,3-Butanediol | HCID 262 | — |
| Reactant | Propylene Glycol | HCID 1030 | — |
| Product | 1,4-Butanediol | HCID 8064 | — |
| Product | 1,5-Pentanediol | HCID 8105 | — |

Reaction Steps
This can be accomplished by a partial replacement of the aforementioned diols by other diols such as 1,2-propane diol and 2,3-butane diol, or by using methyl-substituted dicarbonic acids. By using the aforementioned longer-chained glycols, such as 1,4-butane diol, 1,5-pentane diol and/or 1,6-hexane diol, elastomers of increased hydrolytic stability are obtained.
