    Abstract: A hydrogel composition is formed by conveying separate first and second liquid components subject to a selectively applied application pressure P(A) into an outlet path for mixing and discharge. A liquid flushing agent is automatically conveyed into the outlet path subject to a substantially constantly applied purge pressure P(P) when the application of P(A) is interrupted, to continuously flush residual hydrogel composition from the outlet path.

    Abstract: Provided is a method for multi-information fusion of gas sensitivity and chromatography and on-site detection and analysis of flavor substances using an electronic nose instrument. The electronic nose instrument includes a gas sensor array module (I), a capillary gas chromatographic column module (II), an automatic headspace sampling module (III), a computer control and data analysis module (IV), an automatic lifter (V) for headspace sampling, a large-volume headspace vapor generation device (VI) and two auxiliary gas sources (VII-1, VII-2). In the gas sampling period of T0-300-600 s, the gas sensor array module and the gas chromatography module have different flow rates, volumes and staring sampling time points of gas sampling, but have synchronous selection and analysis time points of multiple sensitive information. The electronic nose instrument obtains a 69-dimensional combined pattern, including steady-state response peak values, corresponding peak time points as well as under-curve areas, through each on-site real-time detection to a tested sample. The electronic nose instrument detects a large number of odorous samples to establish a big odor data. On this basis, the normalization fusion preprocessing is done, and the cascade machine learning model realizes both an on-site recognition of many foods, condiments, fragrances and flavors, and petroleum waxes and a real-time quantitative prediction of their odor quality grades and many key component concentrations.

    Abstract: This invention provides a method for synthesizing glycolide using methyl glycolate as a raw material, comprising two steps as illustrated in the following reaction formulas:




    wherein, the ROH represents a straight/branched chain alcohol, acid or ester containing 18-30 carbons and at least one hydroxyl group. The method for glycolide synthesis disclosed in the present invention manages to maintain a low viscosity within the reaction system by introducing a high-boiling alcohol into the reaction system to form a larger alkoxy glycolate exhibiting a significantly lower molecular weight compared to the typical glycolic acid oligomers utilized in the conventional process. Thus the challenges of coking and inefficient heat transfer encountered in traditional glycolide synthesis routes are effectively addressed.
