Second, the main quality indicators:
Appearance: white or white-like powder
Content: ≥85% Moisture: ≤ 10.0%
Sodium chloride: ≤5.0%
Solubility test (80℃): yellow to light brown transparent liquid (a small amount of insoluble matter is allowed)
PH value: 8.0- 1 1.0.
Properties: Pure product is white-like solid powder, slightly soluble in water. The concentration of saturated solution is about 0.5% in ice water and about 20% in boiling water. Soluble in acetonitrile, methanol, ethanol and other organic solvents, it can be converted into 3,5,6-trichloropyridine -2- alcohol under acidic conditions (melting point 169 ~ 17 1℃).
Third, the use:
Used for producing chlorpyrifos and chlorpyrifos methyl with high efficiency and low residue.
Four, packaging:
Use plastic woven bags lined with polyethylene plastic bags. Net weight of each bag is 25 kg or determined according to customer's needs. Keep the materials dry during storage and transportation, and avoid contact with strong oxidants and acids.
Verb (abbreviation of verb) Plastic woven bag size: 80CM*57CM* 16CM
