Uvitex 2B - Introduction
Optical brightener OB(BBOT) is a fluorescent dye whose full name is phenylacetal thiourea N,N'-diacid (N-ethyloxycarbonyl) amide. The following is a description of the nature, use, preparation and safety information of fluorescent whitening agent OB:
Nature:
-Appearance: Fluorescent brightener OB is a white crystalline powder
-Solubility: Soluble in alcohol, ether and ketone organic solvents, slightly soluble in water
-Melting point: about 160-165°C
-Stability: light resistance, heat resistance, but unstable under alkaline conditions
Use:
Fluorescent whitening agent OB is mainly used as a fluorescent whitening agent and is widely used in plastics, textiles, leather, paper, paint, ink and other industries. It can absorb ultraviolet light and then emit blue-violet or blue-green fluorescence, which has a whitening effect and makes items look whiter and brighter.
Preparation Method:
The fluorescent whitening agent OB can be obtained by reacting phenylacetal with thiourea. First, a phenyl acetal and thiourea are subjected to a condensation reaction in an alkaline solution to produce an acetal thiourea ketone. Then, an N-ethyloxycarbonyl group is introduced into the compound by an acylation reaction to obtain a fluorescent whitening agent OB. The specific preparation conditions and processes will vary and can be adjusted according to specific conditions.
Safety Information:
-Fluorescent whitening agent OB should be used in accordance with safe practice and avoid contact with skin, eyes and respiratory tract.
-During operation and storage, care should be taken to avoid contact with oxidants and strong acids to avoid dangerous reactions.
-fluorescent whitening agent OB may produce certain toxicity to the environment, should pay attention to control the amount of use and correct disposal of waste.
-When using Fluorescent Brightener OB, it is recommended to read the product safety data sheet and follow the relevant safety instructions.
