Ecological data
This substance is harmful to the environment and can cause pollution to water bodies and the atmosphere. Organic acids can easily form acid rain during atmospheric chemistry and atmospheric physical changes. Therefore, when the pH value drops below 5, it will cause damage to animals and plants.. Determination of cerium, copper, lanthanum, scandium, ytterbium, yttrium and nitrite. Separation and determination of iron and aluminum. Gas chromatography standards. Buffer. Organic Synthesis. Manufacture of esters and succinates for paints, dyes, and perfumes. Take photos.
2.Used as alkali method standard reagent, buffer, and gas chromatography comparison sample. Used to test cerium, copper, lanthanum, scandium, ytterbium, yttrium, nitrite, and determine iron and lead.
3.Used as analytical reagents, such as preparing buffer solutions. Chromatographic analysis of standard materials. It is also used in organic synthesis of coatings, dyes, etc.
4.Succinic acid is used as an intermediate for fine chemicals and organic synthesis. Its main application areas include medicine, dyes, and organic pigments. , rubber vulcanization accelerators, alkyd resins, adhesives, lubricants, paper chemicals, plant growth accelerators, photographic chemicals, surfactants, ion exchange resins, pesticides, fungicides and cosmetics, etc.
5.Succinic acid is used in electroless nickel plating and brush chromium plating solutions.
6. Mainly used to prepare five-membered heterocyclic compounds such as succinic anhydride. Used medicinally as an antispasmodic, expectorant and diuretic. Used in analytical chemistry as a reagent to separate iron from other metals. Also used in the preparation of alkyd resins, spray paints and dyes.
