Synthesis of novel N,N-di-n-alkylaldonamides and properties of their surface chemically pure adsorption layers at the air/water interface

Investigations on foamability of surface-chemically pure aqueous solutions of functionalized alkylaldonamides

“…The surfactants under study were obtained according to a procedure described in our previous papers [19][20][21]. The measurements were performed with the homologue series of N,N -di-n-alkylgluconamides, D n GA, and N,N -di-nalkylglucoheptonamides, D n GHA (alkyl: n-C 3 H 7 , n-C 4 H 9 , n-C 5 H 11 , and n-C 6 H 13 ), N-n-alkyl-N -(2-hydroxyethyl)-gluconamides, C n HEGA, and N-n-alkyl-N -(2-hydroxyethyl)glucoheptonamides, C n HEGHA (alkyl: n-C 6 H 13 , n-C 8 H 17 , and n-C 10 H 21 ), and N -cycloalkylgluconamides, c-C n GA, and N -cycloalkylglucoheptonamides, c-C n GHA, …”

Synthesis and Characterization of Glucosamide Surfactant

“…Nonionic surfactants are widely used in many industries. Although conventional nonionic surfactants can be produced in large scale from petrochemical raw materials, the increasing need for biodegradable and less toxic products has led to numerous studies of new sugar-based surfactants, which can be prepared from natural raw materials [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. From the standpoint of human health and ecology, sugarbased nonionic surfactants are an important and possible alternative over conventional surfactants.…”

Carbohydrate-Derived Surfactants

“…Pilakowska-Pietra and collaborators also used Dgluconolactone 35 and D-glucoheptonic-γ-lactone 44 to obtain N,N-di-n-alkyl-substituted amides (Scheme 11) [55]. This type of surfactants, with two long-chain alkyl residues, possess better solubility than the related compounds with one alkyl chain [56,57], and can be applied as cell or membrane units and modifiers [58,59].…”
