Introduction:
Quinoline is an important pharmaceutical raw material, quinoline can be used in niacin, vitamin preparations, stimulants, etc. In addition, quinoline can also be used in the dye industry and rubber industry. Quinoline substances are impurities contained in coal tar wash oil fraction, with a content of about 3% to 5%. At present, most of the washing oil is only used as a benzene absorbent for coke oven gas, fuel oil or raw material for carbon black, etc., making this part of precious resources wasted.
package：
Quinoline should be packed in steel drums with small openings; ordinary wooden boxes outside ampoules; ordinary wooden boxes outside screw-top glass bottles, crimped glass bottles with iron caps, plastic bottles or metal barrels (cans); screw-top glass bottles, plastic bottles or Tin-plated steel drums (cans) are filled with floor grid boxes, fiberboard boxes or plywood boxes.
