What are the upstream raw materials of the alcohol? What do the downstream products contain?

Penediol(pentanediol) has a wide range of applications in the field of chemical production raw materials. The following are some of the upstream and downstream associated items of Psb:



1. Upstream items:(1) Ethylene: Ethylene is one of the main raw materials of the glycol, through the ethylene oxidation method to create ethylene oxide, and then react with aquatic environments to obtain the glycol.(2) Formaldehyde: Formaldehyde is able to react with acetaldehyde under alkaline conditions to obtain a glycol. And For example

2. Downstream items:(1) Polyester resin: The interaction of glycols and terephthalic acid produces polyester resin, which is frequently applied in the production of beverage bottles, films, fibers and other items. Specifically(2) Polyurethane: The interaction of glycols with diisocyanates produces polyurethane, which is frequently applied in the production of foams, elastomers, coatings and other items.(3) Plasticizer: The glycol is able to be applied to create plasticizers, such as phthalate, which is frequently applied in plastic processing to increase the flexibility and plasticity of plastics. But(4) Stabilizer: it's able to be applied to create heat stabilizers, such as stearic acid, which is frequently applied in polyvinyl chloride processing to prevent its thermal decomposition. In short, as an crucial chemical raw material, it has a wide range of applications in the field of chemical production raw materials. And Its upstream and downstream related items cover many fields, such as plastics, rubber, coatings, fibers, etc.
