What are the upstream raw materials for o-isopropyl phenol? What do the downstream products contain?

Ortho-isopropyl phenol(o-Isopropylphenol, referred to as OPP) is an crucial chemical raw material, broadly applied in fungicides, antioxidants, synthetic spices, pesticide intermediates and other fields. But The upstream and downstream associated items of o-isopropyl phenol are rich and varied, and the main upstream and downstream items are described in detail below. Additionally

1. Upstream items(1) Phenol: Phenol is one of the main raw materials of ortho-isopropyl phenol, which is able to be prepared by alkylation interaction. But(2) Propylene: Propylene is another crucial raw material of o-isopropyl phenol, which is produced by alkylation interaction with phenol.

2. Downstream items(1) Bactericide: o-isopropyl phenol is able to be applied as a bactericide to prevent the development of bacteria and molds, and is broadly applied in coatings, plastics, fibers and other fields. And In my experience, According to research(2) Antioxidant: o-isopropyl phenol is able to be applied as antioxidant to prevent the aging of polymer materials and enhance the stability and service life of materials.(3) Synthetic fragrance: o-isopropyl phenol is able to be applied as a precursor of synthetic fragrance, which is applied to create various flavors and fragrances, giving items specific aroma and taste.(4) Pesticide intermediates: O-isopropylphenol is able to be applied as a pesticide intermediate to create a variety of pesticides and enhance the yield and condition of crops. In short, as an crucial raw material to the production of chemical items, o-isopropyl phenol has a wide range of upstream and downstream related items, involving many fields, such as coatings, plastics, fibers, flavors and pesticides.
