    摘要: Poly(lactic acid) blends having a relatively high heat distortion temperature can be prepared by simple blending of PLA polymers of opposite stereoforms, followed by processing, e.g. by injection molding, under specific conditions of temperature and pressure, so as to produce a blend which, on differential scanning calorimetry, exhibits two peaks within the melting range of the stereocomplex. Moreover, by careful selection of these conditions of temperature and pressure, it is possible to use PLA polymers of significantly higher molecular weights than previously thought possible.

    摘要: The present invention relates to novel methods for stabilizing aqueous deacylation, via use of buffers in the production of sucralose. The present invention provides a process for producing sucralose from an acyl-sucralose compound whereby the acyl-sucralose compound is deacylated in the presence of a buffering agent, which stabilizes the pH of the feed mixture and decreases the accumulation of undesired anhydro compounds. Further, the present invention provides a process whereby the acyl-sucralose compound is deacylated directly either prior to or after removal of the tertiary amide reaction vehicle from the neutralized chlorination feed mixture. An aqueous solution of sucralose including salts and other compounds is produced, from which sucralose is recovered by extraction and purified by crystallization.
