What is UV-9?

Ultraviolet absorber is a sort of light stabilizer that can take in the ultraviolet part of sunlight and fluorescent source of lights without altering itself. Under sunlight and fluorescence, plastics and other polymer products will go through an auto-oxidation response because of the action of ultraviolet rays, resulting in the destruction of the polymer as well as degeneration of appearance as well as mechanical properties. After adding ultraviolet absorbers, this high-energy ultraviolet ray can be selectively soaked up and also developed into safe power for launch or consumption.

UV Absorbers are Classified According to Chemical Structure

UV-9 Production Method

A manufacturing method of UV-9, characterized by:
( 1 ), BP-3 crude:

a. Product manufacturing proportion, based upon weight proportion:

2,4-Dihydroxybenzophenone (described as BP-1)) unrefined item 1
n-hexane 0.9-1.2.

Sodium carbonate 0.3-0.4.

Dimethyl sulfate 0.15-0.2.

Water 1.5-2.

b. Mix crude BP-1, n-hexane and also sodium carbonate in the activator in proportion, after that add dimethyl sulfate and warm to produce 2-hydroxy-4-methoxybenzophenone. The response temperature level is 45 -68 ℃, response time is 4-6 hours;.

c. Include water to the response kettle to stratify the fluid, heat it to 68-110 ° C, distill and different n-hexane, as well as discharge the waste water; remain to warmth 110-210 ° C to generate BP-3 distilled unrefined item, which is after that cooled down to regular temperature to get BP- 3 crude item, item web content is 95%, light red;.

c. Include water to the response kettle to stratify the fluid, warmth it to 68-110 ° C, distill as well as separate n-hexane, and discharge the waste water; remain to warmth 110-210 ° C to generate BP-3 distilled crude product, as well as reduced it to regular temperature level to acquire BP-3 unrefined product, item web content is 95%, light red;.

( 2 ), BP-3 refining:

a. Main refining: Include the crude BP-3 item to the methanol remedy, warmth at 55-68 ° C up until the unrefined item BP-3 is fully liquified, centrifuge to remove pollutants, and amazing to 0-10 ° C for condensation;.

b. Secondary refining: Include the main refined BP-3 crystal material to the methanol service, then warmth it at 55-68 ° C till the crude BP-3 item is fully liquified, centrifuge to eliminate impurities, as well as trendy to 0-10 ° C for formation to get BP-3 is a great product, which is gotten after drying out. The item content is ≥ 99.9%, and it is a light yellow powder.
