2-Methyl-2,4-pentanediol (MPD) is an organic compound with the formula (CH 3) 2 C(OH)CH 2 CH(OH)CH 3.This colourless liquid is a chiral diol.It is produced industrially from diacetone alcohol by hydrogenation. [4]
Propylene glycol (IUPAC name: propane-1,2-diol) is a viscous, colorless liquid.It is almost odorless and has a faintly sweet taste. Its chemical formula is CH 3 CH(OH)CH 2 OH. . As it contains two alcohol groups, it is classified as a d
A diol is a chemical compound containing two hydroxyl groups (−OH groups). [1] An aliphatic diol may also be called a glycol. [2] This pairing of functional groups is pervasive, and many subcategories have been identified. They are used as protecting groups of carbonyl groups, making them essential in synthesis of organic chemistry. [3]
Neopentyl glycol (IUPAC name: 2,2-dimethylpropane-1,3-diol) is an organic chemical compound. It is used in the synthesis of polyesters , paints , lubricants , and plasticizers . When used in the manufacture of polyesters, it enhances the stability of the product towards heat, light, and water.
Whole bowel irrigation with polyethylene glycol and added electrolytes is used for bowel preparation before surgery or colonoscopy or for children with constipation. [6] Macrogol (with brand names such as Laxido, Movicol and Miralax) is the generic name for polyethylene glycol used as a laxative. The name may be followed by a number that ...
It is a cyclic carbonate ester derived from propylene glycol. [4] This colorless and odorless liquid is useful as a polar , aprotic solvent . [ 5 ] Propylene carbonate is chiral , but is used as the racemic mixture in most contexts.
Polypropylene glycol is produced by ring-opening polymerization of propylene oxide. The initiator is an alcohol and the catalyst a base, usually potassium hydroxide. When the initiator is ethylene glycol or water the polymer is linear. With a multifunctional initiator like glycerine, pentaerythritol or sorbitol the polymer branches out ...
