The invention discloses spirulina alpha-glucan containing soluble dietary fibers and having immunomodulatory activity and a preparation method thereof, spirulina is subjected to continuous illumination culture under nutrient salt deficiency or low temperature or combined regulation and control of low temperature and nutrient salt deficiency; a large amount of alpha-glucan which contains more soluble dietary fibers and has immunoregulatory activity is accumulated in the spirulina, and the spirulina alpha-glucan is prepared by adopting a method of hot water extraction, trichloroacetic acid deproteinization and ethanol precipitation. The prepared spirulina alpha-glucan contains 10%-26% of dietary fibers, the content of the dietary fibers is 9-27 times higher than the content of the dietary fibers of maltodextrin, the spirulina alpha-glucan can induce secretion of NO, TNF-alpha and IL-6 of macrophages RAW264.7, the activation index of the NO reaches 1.5-3.6, the activation index of the TNF-alpha reaches 2.0-4.1, the activation index of the IL-6 reaches 1.6-3.0, and the spirulina alpha-glucan has a remarkable immunoregulation effect. Technical support and product cases are provided for development of spirulina glucan type high-added-value functional products.

The invention discloses a method for industrialized continuous production of 4-chlorobenzaldehyde dimethyl acetal: p-chlorobenzaldehyde, trimethyl orthoformate and a catalyst are introduced into a synthesis reactor at a designed flow rate, and the synthesis reactor continuously produces qualified products. The continuous productivity of the entire process is maintained by designing factors such as the material molar ratio, the residence time of the material in the synthesis reactor, the temperature, the pH and the pressure. Compared with intermittent production, continuous production has obvious advantages: no solvent is required; the annual output of the product is large; the product quality is high; the raw material conversion rate is high; the degree of automation is high; the heat release is uniform, and the safety factor is high.
