Isophthalyl ether (IPE) is an important chemical raw material, which is widely used in medicine, pesticide, dye, perfume and other fields. The following are the upstream and downstream related products of isophthalic ether:

upstream products:

1. isophthalic acid: isophthalic acid is the main raw material for the production of isophthalic ether, which is produced by esterification.
2. Methanol: Methanol is used as a catalyst and reaction medium for esterification reaction and reacts with isophthalic acid to form isophthalic ether.

Downstream Products:

1. Pesticides: Isophthalyl ether can be used to produce a variety of pesticides, such as pesticides, fungicides, etc.
2. Pharmaceutical intermediates: m-phenylene ether can be used as pharmaceutical intermediates for the production of anti-tumor, anti-cardiovascular drugs.
3. Dyes: Isophthalyl ether can be used to produce a variety of dyes, such as acid dyes, direct dyes, etc.
4. spices: isophthalic ether can be used as a precursor of spices for the production of food additives and spices for daily chemical products.

Specifically, the upstream and downstream associated products of isophthalic ether include but are not limited to the following aspects:

Upstream products:

1. isophthalic acid: isophthalic acid is the basic raw material for the production of isophthalic ether, and isophthalic acid is converted into isophthalic ether through a chemical reaction.

Downstream Products:

1. Pesticides: Isophthalic ether can be used to produce pesticides, fungicides and other pesticides. It has the characteristics of broad spectrum and high efficiency, and is of great significance for the prevention and control of crop diseases and insect pests.
2. Pharmaceutical intermediates: m-phenylene ether can be used as pharmaceutical intermediates to further synthesize anti-tumor, anti-cardiovascular and other drugs, which play an important role in the treatment of diseases.
3. Dyes: m-benzene ether can be used to produce a variety of dyes, such as acid dyes, direct dyes, etc., these dyes are widely used in textile, printing and dyeing industries.
4. spices: m-phthalic ether can be used as a precursor of spices, and further synthesize food additives and spices of daily chemical products, providing important flavor components for food, cosmetics and other industries.

In short, the upstream and downstream related products of isophthalic ether are very extensive, involving many fields, such as pesticides, pharmaceuticals, dyes, spices, etc. These products are closely related to people's daily life and industrial production, so the production and development of m-phthalide is of great significance.
