ETB (ethyl tert-butyl ether) is a common raw material for chemical production, which is widely used in fine chemicals, pharmaceuticals, pesticides and other fields. The upstream and downstream associated products of ETB mainly include the following aspects:

1. Upstream products

(1) Ethanol: Ethanol is one of the main raw materials for the production of ETB, and ETB is obtained by reacting with isobutylene.

(2) Isobutene: Isobutene is another feedstock for the production of ETB, typically sourced from crackers in the petrochemical industry.

2. Downstream Products

(1) Ethyl tert-butyl hydroperoxide (ETBH):ETBH is a commonly used oxidant that can be prepared by reacting ETB with hydrogen peroxide.

(2) Ethyl tert-Butyl Sulfide (ETBS):ETBS is a commonly used sulfiding agent and can be prepared by reacting ETB with a sulfiding agent.

(3) Ethyl tert-Butylamine (ETBA):ETBA is an organic amine compound used in the preparation of rubber accelerators and other fine chemicals.

(4) Ethyl tert-butyl chloride (ETBC):ETBC is an organic chloride, which can be used to prepare pesticides, pharmaceutical intermediates, etc.

above is only a part of the upstream and downstream related products of ETB, in fact, ETB as an important organic synthesis intermediate, its application field is very wide, can also be used to prepare many other fine chemicals.
