the method of calculation of free LAS monomer
The computation model of CMC and monomer-micelle composition is based on puppet-be separated model and regular solution theory.Puppet-the model description that is separated in " Non-ideal multicomponent mixed micellemodel ", Holland, P.M.; Rubingh, D.N., J.Phys.Chem.1983,87 (11), 1984-1990.Regular solution theory is described in " Micellization of mixed nonionic surface-activeagents ", Clint J.H., J.Chem.Soc., Faraday Trans.1 1975,71,1327-1334.The tensio-active agent interphase interaction (that is, β parameter) in the composition of described surfactant formulations, the CMC of single tensio-active agent and mixed micelle to the input of this computation model.
Described puppet-be separated the CMC of model for gauging surface active agent intermixture.In this model, then think that described tensio-active agent is present among the two-phase of balance mutually more than CMC: the micellar phase of gathering and the monomer phase of non-agglomerated.Based on this two-phase approximation theory, given surfactant materials partial potential in each phase can be calculated as:
For monomer phase,
For micellar phase,
In addition, for be in or higher than the pure surfactant soln of its CMC, monomer concentration fixedly equals this CMC concentration.Because described solution is equal with micella partial potential, pure system following relationship is set up:
When balancing, the partial potential of given material is equal in two-phase, that is, (1)=(2).Therefore, by merging equation (1), (2) and (3) and must following relationship:
For mixture C MC, following relationship is effective:
By merging equation (4) and (5) and suing for peace to described material, the CMC of this mixture is calculated as:
For the activity quotient γ i in accounting equation (6), refer to regular solution theory.By regular solution theory, simple Activity Coefficient Models is derived as follows:
Regular solution theory allows rough by single interaction parameter but the specificity between the surfactant types of successfully catching interacts.In real surfactant mixture, the cooperative interaction of β parameter regularly between reverse reflection tensio-active agent.
At " Surfactants and Interfacial Phenomena ", Rosen, M.J., WileyInterscience:New York, in 1989, β parameter bunch integrated group based on surfactant types, as summarized in Table 1.
table 1
For calculating nonideal mixture C MC, equation (7) and following equations are merged and iterative.
Equation (4) is rearranged to material i and j,
In equation (8), material j is sued for peace,
Initial to equation (7), (8) and (9) iterative with the estimated value of activity quotient subsequently.Particularly, the step related in iteration comprises:
1) at the beginning, valuation is made to activity quotient.A selection is that the desirable micella of hypothesis comes initial, and wherein all activity quotient is 1.
2) based on one group of activity quotient, (9) are resolved with the new valuation of the micella molfraction of Calculation Basis component, x
i.Use x
ithe new valuation of all the other micellar fractions is calculated with (8).
3) new micella composition is used to generate new activity quotient with (7).If old converges with new activity quotient, then obtain the solution from being in harmony.Otherwise return step 2 and continue iteration until converge.
Once known nonideal CMC, then next step is the amount that each material of calculating exists as monomer and micella.Under CMC, this system exists as monomer completely, and described monomer concentration equals integral value.On CMC, following relation is needed the micella molfraction of given material to be associated with primary standard:
Following relation is the restriction of based on molfraction summation:
(10) are substituted into the expression formula that benchmark molfraction is resolved in (11) valuation created based on activity quotient.X
itherefore, the identical solution procedure used for imperfect CMC can be used, replace except (8)-(9) except by (10)-(11).Once micella molfraction and activity quotient are from trying to achieve with being in harmony, (4) are used to produce monomer concentration.
Wherein at equation (1) above in (11):
Therefore, for the surfactant mixture or the aqueous solution that comprise LAS, the content of free LAS monomer can as above describe to calculate, and wherein material i represents LAS and material j and k represents one or more cosurfactants.
