“…The molar fraction of liquid toluene in the micronized mixtures is varied between x T = 0.3-0.8. Using the NRTL-model (Messow and Engel 1977) for the liquid phase and under the assumption that the gas phase is ideal, the composition of the gas phase in the primary solutions can be calculated, so that a relation between the Raman intensity and the gas phase concentration of toluene can be established.…”

In this work the feasibility of Raman spectroscopy, especially the detection limit of this technique for the chemical characterization of multicomponent aerosols, which appear in technical processes has been investigated. In such kind of aerosols high number concentrations (>10 6 cm The characterization of the aerosols with Raman spectroscopy with respect to their gas phase is without any difficulty, whereas the analysis in the dispersed phase is partially marginal and in majority of cases almost not possible.Especially for the reaction aerosols rejection of elastically scattered light is the principle limitation in collecting Raman scattered light from particles in the Mie-scattering regime.

“…Results for m are: 1.28 (2-propanone); 1.05 (3-pentanone); 0.39 (DMC); 0.31 (DEC). However for systems with a given alkane, say dodecane, UCST/K ¼ 286.2 (2-propanone) [117] < 307.61 (DMC) [51]. Similarly, H E m and U E V m values are also lower for alkanone mixtures including alkanes (Table S1; supplementary material).…”

Andrés ( ), Marta (MG 2 ), Cristina ( ) y María (mmorped), el resto de mis grandes amigos de la carrera, merecen también un hueco en estas páginas. Espero que tras el caos que nos dispersa siempre tengamos esos momentos de reencuentro.Otro que me ha hecho compañía durante todos mis años universitarios ha sido el hermano pequeño gordo de la familia, Pepo. Supongo que se habrá preguntado por qué pasaba tantas horas fuera o "sin hacer nada" (trabajando) en lugar de haciéndole caso.Por supuesto, quiero dar las gracias a mis padres (María del Mar y Luis) por ser los mejores que podría tener. Gracias por enseñarme que madurar como persona no significa no poder pedir ayuda cuando la necesitas. Y por animarme siempre a hacer lo que realmente me gusta y apoyarme para ello, pues esto es, sin duda alguna, un factor muy importante para ser feliz en la vida.Una felicidad que es completa gracias a Marta. Por ser mi compañera de vida, por aguantar la incertidumbre que supone mi decisión de dedicarme al mundo de la ciencia, y porque errar es de humanos y herrar es de herreros. Hemos recorrido mucho camino juntos, y por ello mi crecimiento como persona, si es que ha habido alguno, es mayoritariamente gracias a ti.Por último, quiero escribir unas líneas para aquellos que nos han dejado durante estos duros años. Vosotros también habéis sido, y seguís siendo, referentes en mi vida. Mere, que nos contagiabas a todos con tu optimismo y alegría. José, grande, generoso y honrado: ya puedes decir por ahí que tu sobrino es por fin Doctor en Física. Padrino, siempre dispuesto a ayudar a todos, un segundo padre para mí. Todos estáis hoy conmigo, en mi corazón y en el de toda la familia, y sois parte indiscutible de esta Tesis.En Valladolid, a 3 de julio de 2019 13 The structure of this ThesisThis Thesis is written as a "PhD Thesis with publications". In order to unify the different works carried out, we proceed now to describe briefly the structure of the Thesis and the relations among its parts.Part I aims to give a global vision of the work performed in this Thesis, describing the pursued objectives (Chapter 1) and the selected experimental and theoretical methodology to accomplish them (Chapters 2 to 4).• Chapter 1 describes all the work performed during these four years and the main goals of the Thesis.• Chapter 2 summarizes the studied thermodynamic properties and notation, assuming that the reader has some previous knowledge about the subject.• In Chapter 3, the experimental equipment and methodology are described in detail, since much of the information about calibration and test of the techniques is not provided in the publications included in this Thesis. This is the only part of the manuscript that is written in spanish, so that future students in the University of Valladolid find easier to start working in our laboratory.• The theoretical models used are described in Chapter 4. It includes information not given in the publications, and also some original contributions.The results in complete form are given in Part II as copies of...

in Wiley InterScience (www.interscience.wiley.com). Accounting for dipolar interactions in a physically based equation of state (EOS) can substantially improve the modeling of phase equilibria of real mixtures. An EOS contribution for dipolar interactions of nonspherical molecules is developed based on a third-order perturbation theory. Molecular simulation data for vapor-liquid equilibria of the two-center Lennard-Jones (2CLJ) plus pointdipole fluid is used to determine model constants of the EOS. The resulting model is compared to simulation data of pure dipolar nonspherical molecules and their mixtures and an excellent agreement is found. The proposed dipole term is applied to real substances with the perturbed-chain statistical associating fluid theory (PC-SAFT) EOS and it is confirmed that accounting for dipolar interactions not only reduces the binary interaction parameter, but also improves the
