  The method comprises (1) a carboxylic acid salt providing step comprising permitting a strain of microorganism or a preparation derived from the microorganism to act upon a nitrile to thereby (a) provide at least the corresponding amide which is then hydrolyzed in the presence of a base to provide a salt of the corresponding carboxylic acid or (b) provide a salt of the corresponding carboxylic acid and (2) an electrodialysis step comprising subjecting the carboxylic acid salt provided in the step (1) to electrodialysis to provide the corresponding carboxylic acid and base. Carboxylic acids can be produced without formation of ammonium hydrogen sulfate and other byproducts. The microorganism includes microorganisms of the genera Pantoea and Gordona. The ammonia formed in the step (1) can be reused as a nitrogen source in a nitrile production line.

  The invention relates to a method of testing silanization, which permits inline control of the in situ silanization of light-colored fillers, especially precipitated silicas. This enables continuous in situ silanization in the production of rubber mixtures comprising silanized light-colored fillers, and representative control of the rubber mixture under production conditions. The process is additionally nondestructive and has a high tolerance for carbon black as an additional constituent of the rubber mixture.

  本发明涉及一种硅烷化测试方法，该方法可在线控制浅色填料，特别是沉淀白炭黑的原位硅烷化。这样就能在生产包含硅烷化浅色填料的橡胶混合物时进行连续的原位硅烷化，并在生产条件下对橡胶混合物进行有代表性的控制。此外，该工艺无破坏性，对作为橡胶混合物附加成分的炭黑具有很高的耐受性。
• Process for preparing a multi-layer article having a fluoroplastic layer and an elastomer layer

  A method for enhancing the bond strength between a VDF-containing fluoroplastic layer and an elastomer layer of a multi-layer article. A VDF-containing fluoroplastic composition is applied to the surface of a precursor article that includes a curable elastomer layer to form a fluoroplastic layer. Prior to application of the fluoroplastic composition, the curable elastomer layer is thermally insulated to prevent it from undergoing substantial heating. Following application, the fluoroplastic layer is heated and the curable elastomer layer is cured (e.g., thermally cured). Preferably, the elastomer cure occurs separately from and subsequent to heating the fluoroplastic layer. The combination of thermally insulating the curable elastomer layer prior to application of the fluoroplastic composition and heating the fluoroplastic layer following application of the fluoroplastic composition results in formation of a strong bond between the fluoroplastic and elastomer layers upon cure.

  一种增强多层制品的含 VDF 氟塑料层和弹性体层之间的粘合强度的方法。将含 VDF 的氟塑料组合物涂在包括可固化弹性体层的原制品表面，形成氟塑料层。在使用氟塑料组合物之前，对可固化弹性体层进行热绝缘，以防止其受到大量加热。涂抹后，加热氟塑料层，固化弹性体层被固化（如热固化）。最好是在加热氟塑料层之后单独进行弹性体固化。在涂抹氟塑料组合物之前对可固化弹性体层进行热绝缘，在涂抹氟塑料组合物之后对氟塑料层进行加热，这两种方法的结合可在固化时在氟塑料层和弹性体层之间形成牢固的粘合。
