Vitamins are a huge family. There are dozens of vitamins known today, which can be roughly divided into two categories: fat-soluble and water-soluble. (See the table below for details) Some substances are similar to certain vitamins in chemical structure and can be converted into vitamins through simple metabolic reactions. Such substances are called provitamins. For example, β-carotene can be converted into vitamin A; 7- Dehydrocholesterol can be converted into vitamin D3; but tryptophan, which requires many complex metabolic reactions to become niacin, cannot be called provitamin.

【Introduction】

Name: Ethyl Cellulose

Abbreviation: EC

Structural formula:

In the formula , n stands for degree of polymerization and R for –H or –C2H5 .

Characteristics:

Ethyl Cellulose is a kind of white grains or powder, having no smell or tastes . Its 5% soliquoid shows neutral to litmus test paper . Its specific density 1 . 07~1 . 18 , heat distortion point: 135~155degree centigrade , and fire point: 330~360 degree centigrade . Ethyl Cellulose has good stability to light , heat , oxygen and wetness , and is stable to chemicals . It is resistant to alcali , dilute acid and salting liquid , soluble in some organic solvents , such as alcohol , ether, ketone , ester, aromatic hydrocarbon and halohydrocarbon , etc , and compatible to many celluloses , resin and nearly all plasticizers . Ethyl Cellulose has low combustibility, small hydroscopicity and good electric behavior . Its thin film and plastics have good mechanical strength and flexibility in a wide range of temperature .
