Caprolactam (CPL) is an organic compound with the formula (CH 2) 5 C(O)NH. This colourless solid is a lactam (a cyclic amide ) of caproic acid . Global demand for this compound is approximately five million tons per year, and the vast majority is used to make Nylon 6 filament, fiber, and plastics.
Although no longer economical, caprolactone was once produced as a precursor to caprolactam. Caprolactone is treated with ammonia at elevated temperatures to give the lactam: (CH 2) 5 CO 2 + NH 3 → (CH 2) 5 C(O)NH + H 2 O. Carbonylation of caprolactone gives, after hydrolysis, pimelic acid. The lactone ring is easily opened with nucleophiles ...
Their common names are β-propiolactam, γ-butyrolactam, δ-valerolactam, and ε-caprolactam. A lactam is a cyclic amide, formally derived from an amino alkanoic acid through cyclization reactions. The term is a portmanteau of the words lactone + amide.
Palmitoleic acid has 16 carbons, is found in cod liver oil, sardine oil, and herring oil, and is a cis-9-monounsaturated fatty acid. C 15 H 29 CO 2 H, IUPAC organization name (Z)-hexadec-9-enoic acid, n-7, numerical representation of 16:1, molecular weight 254.41, melting point 5 °C, specific gravity 0.894. CAS Registry Number 373-49-9.
An unsaturated fat is a fat or fatty acid in which there is at least one double bond within the fatty acid chain. A fatty acid chain is monounsaturated if it contains one double bond, and polyunsaturated if it contains more than one double bond.
Caprolactam molecule used to synthesize Nylon 6 by ring opening polymerization. Nylon 6 or polycaprolactam is a polymer, in particular semicrystalline polyamide.Unlike most other nylons, nylon 6 is not a condensation polymer, but instead is formed by ring-opening polymerization; this makes it a special case in the comparison between condensation and addition polymers.
A new study has found that consuming 6 milligrams of the coffee compound cafestol twice daily for 12 weeks might help reduce weight and body fat but not improve insulin sensitivity or glucose ...
For this reason it is effective in treatment of certain bleeding disorders, and it is sold under the brand name Amicar. [3] Aminocaproic acid is also an intermediate in the polymerization of Nylon-6, where it is formed by ring-opening hydrolysis of caprolactam. The crystal structure determination showed that the 6-aminohexanoic acid is present ...
