Flash point (FP) is an important parameter to assess chem. compound safety. Many empirical approaches have been developed to predict FP based on mol. structure, sometimes involving a large number of descriptors and resulting in class-specific equations. This work demonstrated that a satisfying, rather general prediction of saturation pressure at the FP can be achieved using only mol. surface area. This relation in conjunction with any exptl. or computational method to calculate temperature-dependent vapor pressures allows for the FP predictions. In a second step, chem. mixture FP were calculated using COSMO-RS activity coefficients Using the proposed method, FP were calculated without needing data typically generated in experiments (normal b.p., combustion enthalpy), although exptl. pure-compound FP and vapor pressure data can still be used to increase prediction quality. This study involved multiple reactions and reactants, such as Ethyl 3-ethoxypropanoate (cas: 763-69-9Application In Synthesis of Ethyl 3-ethoxypropanoate).
Ethyl 3-ethoxypropanoate (cas: 763-69-9) belongs to esters. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Application In Synthesis of Ethyl 3-ethoxypropanoate
