Hansen solubility parameters were developed by Charles M. Hansen in his Ph.D thesis in 1967 as a way of predicting if one material will dissolve in another and form a solution. They are based on the idea that like dissolves like where one molecule is defined as being 'like' another if it bonds to itself in a similar way. Specifically, each molecule is given three Hansen parameters, each generally measured in MPa0.5: * The energy from dispersion forces between molecules * The energy from dipolar intermolecular force between molecules * The energy from hydrogen bonds between molecules.

  • ハンセン溶解度パラメーター(Hansen solubility parameter, HSP)は、Charles M. Hansenが1967年に博士論文で発表した、物質の溶解性の予測に用いられる値である。 HSPは「分子間の相互作用が似ている2つの物質は、互いに溶解しやすい」との考えに基づいている。HSPは以下の3つのパラメーター(単位:MPa0.5)で構成されている。 * : 分子間の分散力によるエネルギー * : 分子間の双極子相互作用によるエネルギー * : 分子間の水素結合によるエネルギー これら3つのパラメーターは3次元空間(ハンセン空間)における座標とみなすことができる。そして2つの物質のHSPをハンセン空間内に置いたとき、2点間の距離が近ければ近いほど互いに溶解しやすいことを示している。あるポリマーがある溶媒に対して可溶であるかどうかの予測は次の方法で行う。ポリマーが相互作用半径という値を持っており、ポリマーのHSPの座標を中心とした半径の球がハンセン空間内にあるものと仮定する。また、ポリマーのHSPと溶媒のHSPの間の距離は以下の式によって計算される。 (ja)

  • Hansen solubility parameters were developed by Charles M. Hansen in his Ph.D thesis in 1967 as a way of predicting if one material will dissolve in another and form a solution. They are based on the idea that like dissolves like where one molecule is defined as being 'like' another if it bonds to itself in a similar way. Specifically, each molecule is given three Hansen parameters, each generally measured in MPa0.5: * The energy from dispersion forces between molecules * The energy from dipolar intermolecular force between molecules * The energy from hydrogen bonds between molecules. These three parameters can be treated as co-ordinates for a point in three dimensions also known as the Hansen space. The nearer two molecules are in this three-dimensional space, the more likely they are to dissolve into each other. To determine if the parameters of two molecules (usually a solvent and a polymer) are within range, a value called interaction radius (R0) is given to the substance being dissolved. This value determines the radius of the sphere in Hansen space and its center is the three Hansen parameters. To calculate the distance (Ra) between Hansen parameters in Hansen space the following formula is used: Combining this with the interaction radius gives the relative energy difference (RED) of the system: * RED < 1 the molecules are alike and will dissolve * RED = 1 the system will partially dissolve * RED > 1 the system will not dissolve (en)
  • Il parametro di solubilità di Hansen è un coefficiente sperimentale introdotto da per predire la solubilità di un soluto (ad esempio un polimero) in un solvente. La definizione del parametro di Hansen discende dall'osservazione sperimentale che "il simile scioglie il simile", per cui si forma una soluzione se l' del soluto nel solvente è paragonabile all'energia che si esplica tra le molecole di soluto puro. Per avere una migliore predizione, l'energia di dissoluzione viene inoltre scomposta da Hansen in 3 contributi, per cui si deve avere la somiglianza di tutti e tre questi contributi, che sono: * : energia delle forze di dispersione (forze di van der Waals) * : energia associata ai Legami intermolecolari dipolari * : energia associata ai legami idrogeno. Per verificare la solubilità di un soluto in un determinato solvente, si traccia anzitutto in uno spazio tridimensionale (detto "spazio di Hansen") una sfera centrata nel punto e con raggio pari a: in cui gli apici "1" e "2" si riferiscono rispettivamente al solvente e al soluto. Quindi si individua nello spazio di Hansen il punto corrispondente al solvente, e a seconda della posizione reciproca di tale punto rispetto alla sfera rappresentativa del soluto si realizzerà uno dei seguenti casi: * il punto rappresentativo del solvente sta dentro la sfera rappresentativa del soluto: si ha miscibilità totale; * il punto rappresentativo del solvente sta sulla superficie della sfera rappresentativa del soluto: si ha miscibilità parziale; * il punto rappresentativo del solvente sta fuori dalla sfera rappresentativa del soluto: in questo caso non si ha miscibilità.
