307-40-4 Usage
General Description
Perfluorodecanamide, also known as Nonafluorodecanamide, is an organic compound with a general formulation of C10HF20NO. It is recognized to be a fluorinated substance, employing full fluorination of all its carbon atoms. This chemical is insoluble in water and commonly utilized in several industrial applications due to its resistance against oil, chemicals, and heat - characteristics associated with fluorochemicals. As a consequence, its increased usage raises environmental concerns due to its bioaccumulation potential and toxicity. From a safety standpoint, it is significant to handle this chemical moderately with proper protection since it can lead to eye and skin irritation and even severe eye and skin burns.
Check Digit Verification of cas no
The CAS Registry Mumber 307-40-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,0 and 7 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 307-40:
(5*3)+(4*0)+(3*7)+(2*4)+(1*0)=44
44 % 10 = 4
So 307-40-4 is a valid CAS Registry Number.

Micelle Formation in Liquid Ammonia

Perfluorinated long chain alkyl amides aggregate in liquid ammonia with increasing concentration which reflects micelle-type formation based on changes in 19F NMR chemical shifts. The critical micelle concentrations (cmc) decrease with increasing chain length and give Kleven parameters A = 0.18 and B = 0.19. The micelles catalyze the ammonolysis of esters in liquid ammonia. The corresponding perfluorinated long chain alkyl carboxylates form ion pairs in liquid ammonia, but the equilibrium dissociation constants indicate favorable interactions between the chains in addition to the electrostatic forces. These perfluorinated carboxylates form micelles in aqueous solution, and their cmc's generate a Kleven B-value = 0.52 compared with 0.30 for the analogous alkyl carboxylates. The differences in hydrophobicity of CH2 and CF2 units in water and liquid ammonia are discussed, as is the possible relevance to life forms in liquid ammonia.
