Molecular Weight: 696.25
Appearance    powder.
Solubility    soluble in water.
Stability    stable in alkali, weak acid and hard water; unstable in strong acid, hydrolyzed.
Risk    Solid form: irritation, irritation to skin, eye.
GHS (Rev.6) label:  
Ecology    may be hazardous to environment. Water body should be given special attention.
Biodegradability    biodegradable.
Characteristics    excellent dyeing, masking, dispersing abilities. Solubilized vat dye.
Currently, sulfated reaction through continuous reactor (such as: falling film reactor) is the most widely used method for preparing sulfates.
Generally, vat orange 1 and sulfur trioxide react through reactor, then sodium hydroxide neutralizes, finally obtain product.
