摘要： A retractable safety syringe comprises a needle body, a syringe barrel, and a pusher plunger. The needle body has a needle and a needle seat having an upper needle seat and a lower needle seat; the upper needle seat is used for fixing the needle thereon and is provided with a connecting portion on the bottom; and the removable lower needle seat can be embedded to the upper needle seat from below. The pusher plunger has a piston in the front end thereof; the piston has a connecting member, which can connect to the connecting portion on the bottom of the upper needle seat, so that after injection, by applying a force to press and deform the piston till connecting to the connecting portion, the needle body can depart from the needle socket and the abutment and can be drawn back to the interior of the syringe barrel.

摘要： A process for preparing carboxylic esters. A catalytic distillation column filled with acidic catalyst in solid phase is utilized. Alcohol is fed from the bottom of the catalytic distillation column, and carboxylic acid or carboxylic anhydride is fed from the top of the catalytic distillation column in such a manner that the carboxylic acid or carboxylic anhydride can remain in the catalytic distillation column for a sufficient time to cause the esterification to produce the carboxylic ester and water. An esterification pre-reactor can be connected in series with the catalytic distillation column to facilitate the esterification.

摘要： A disposable safety self-destroyed syringe comprises a plunger and a syringe tube. An end of the plunger is sleeved with a piston, and an elastic protrusive column is coupled inside the piston with its front end being protruded to a distance from a top surface of the piston; the plunger is inserted into the syringe tube from its front end for injection, and the rear end of the syringe tube is contracted radially to form a needle seat having a blocking portion on the inner wall to be conjoined with a needle, so that when the plunger is depressed to reach closely to the rear end of the syringe tube, a front end of the protrusive column is inserted into the needle seat and is stopped by the blocking portion on the inner wall of the needle seat to retain the protrusive column inside the needle seat.
