Japanese term

濃厚相と希薄相

Japanese to English Law/Patents Chemistry; Chem Sci/Eng polyarylene sulfide manufacturing method
I'm thinking of translating
濃厚相と希薄相とからなる液-液相分離状態を形成させる
into
"forming a liquid-liquid phase-separated system comprising a condensed phase and a diluted phase."

However, I've also found
"thick phase and thin phase,"
"continuous phase and dispersed phase" and
"concentrated phase and dilute phase"
on various webpages about phase separation. Are all of these pairs of terms synonymous? Have I picked the correct ones?

Here's the context:
有機アミド溶媒中で、アルカリ金属硫化物とジハロ芳香族化合物とを反応させてポリアリーレンスルフィドを製造する方法において、(A)有機アミド溶媒、ア ルカリ金属硫化物、及びジハロ芳香族化合物を含有する混合物を加熱して反応させるとともに、反応開始後から反応終了前までの間の所望の時点で、反応系内に 水を添加し、それによって、生成ポリマーの濃厚相と希薄相とからなる液-液相分離状態を形成させるに足る量の水を存在させ、次いで、反応終了まで加熱反応 を継続させ、そして、(B)反応終了後、有機アミド溶媒、生成ポリマー、水、及び副生アルカリ金属ハライドを含有する反応混合物から、有機アミド溶媒を蒸 発または蒸留させて回収する各工程を含むことを特徴とするポリアリーレンスルフィドの製造方法。

Concentrated phase and diluted phase

Hi,

Coming from a Chemical engineering background, my comments would be as follows:

"thick phase and thin phase"
- I dont think these terms are used very commonly

"continuous phase and dispersed phase"
- These terms have little different meaning. Considering the context, I dont think 濃厚相/希薄相 can be translated as continuous and dispersed phase.

"concentrated phase and dilute phase"
- Seems appropriate.

You can refer to the research paper on "Liquid-liquid phase separation in polydisperse polymer solutions: The distribution coefficient" available at the following URL. "Diluted phase" and "Concentrated phase" are used at several places in the paper.

thick phase and dilute phase

In the given contect I would suggest this solution although many alternatives can also be accepted
