Abstract: A heterogeneous catalytic chlorination process for making chlorinated aromatic compounds with high para-selectivity. Examples of chlorinated aromatic compounds that can be prepared using the process disclosed in the present invention include those compounds represented by the following formula: ##STR1## wherein R can be a C1-C3 alkyl, floride, chloride, bromide, iodide, or hydroxyl group. The chlorination process utilizes a de-aluminated zeolite which is prepared by H.sub.4 EDTA or Na.sub.4 EDTA extraction of L-type zeolite to reduce the alumina content thereof. The SiO.sub.2 /Al.sub.2 O.sub.3 ratio of the de-aluminated zeolite is preferably between about 9 and about 40. The de-aluminated zeolite can be ion-exchanged with Group IA or IIA metal ions to further improve its para-selectivity.

Abstract: An improved process for the esterification of carboxylic acid and alcohols into carboxylic ester is disclosed. It comprises the steps of: (a) charging the esterification reactants into a fixed bed reactor under a predetermined reaction condition; and (b) reacting the esterification reactants in the fixed bed reactor. The fixed bed reactor contains acidic catalysts that are present in a solid phase, and the reaction condition is controlled such that (i) the reactants and the products co-exist in a gas-liquid two-phase equilibrium in the fixed bed reactor and that (ii) at least one component of the reactants is present in one phase and at least one component of the products is present in another phase. Because a phase change is always taking place concurrently with the esterification reaction; the reaction stream is maintained at a relatively uniform temperature. This greatly reduces the chances of catalyst poisoning and minimizes the formation of undesired by-products such as polymers/oligmers and ethers, which are often produced at high temperatures. The concurrent phase change also contributes to the extremely high reaction yield and selectivity, typically better than 90%, observed in the present invention.

Abstract translation: 公开了一种将羧酸和醇酯化成羧酸酯的改进方法。 它包括以下步骤：（a）在预定的反应条件下将酯化反应物装入固定床反应器; 和（b）使酯化反应物在固定床反应器中反应。 固定床反应器含有存在于固相中的酸性催化剂，并且控制反应条件使得（i）反应物和产物在固定床反应器中以气液两相平衡共存，而且 （ii）反应物的至少一种组分存在于一相中，并且产物的至少一种组分存在于另一相中。 因为酯化反应总是同时发生相变; 反应流保持在相对均匀的温度。 这大大降低了催化剂中毒的机会，并最大限度地减少了常常在高温下生产的不需要的副产物如聚合物/低聚物和醚。 同时的相变也有助于在本发明中观察到的非常高的反应产率和选择性，通常优于90％。
