MANNITOL

Molecular formula : C6H8(OH)6 Molecular weight:182.17

 

Manily used in pharmaceutical industry:

a. As injeaion material or auxiliaty material for tablets Mannitol, not absorbable by oral administration, is often applied by venous injection with 20% high osmolar solution, which pushes the moisture of the solution to disperse in the blasm and result in dewater.

b. Precaution of acute adynamia of kidney function.

c. Remedy for glaucoma and dropsy.

f . Can be used to synthesize mannitol ester nicotinate.

Mannitol used in other industry:

a. To produce tooth paste taking the place of glycerol

Except in brume proof, other quality of tooth paste manufactured by mannitol instead of glycerol such as PH, heat resistance, heat proof stickness, stability are all in conformity with standard.

b. Synthesizing of mannitol rigid poly urethane foam

Epoxy propane polyether synthesized by mannitol and epoxy propane can be used to produce rigid poly urethane foam which has the following characteristics: high mechanical strength, high heat resistance, better aainst weathering ageing, long sewice life, good foamy formation, stable and even quality of finished products, comparatively low consumption of isooxygenate ester.

c. After being dewatered, mannitol can be synthesized together with oleic ester into mannitol anhydride oleic ester, used as emulsifier, corrosion inhibitor in pestcide, chemical, textile, machinery processing.
