    Abstract: An ethanolamine, preferably diethanolamine, is converted to triethylenediamine or 1,4-bis(2-hydroxyethyl)piperazine, or both by pyrolysis using a B-subgroup metal oxide such as titanium dioxide or zirconium dioxide, as catalyst. In addition it has also been discovered that 1,4-bis(2-hydroxyethyl)piperazine and N-(2-hydroxyethyl)piperazine can be converted in high yields and conversions into triethylenediamine by pyrolysis using the same type of catalyst. When using an ethanolamine as the feedstock and a Group IV-B metal oxide as the catalyst, the process usually results in the coproduction of triethylenediamine and 1,4-bis(2-hydroxyethyl)piperazine, and the latter can be recovered and used as a raw material for the production of additional triethylenediamine, as by recycle to the same reactor or as feedstock to an additional pyrolysis reactor.

    Abstract translation: 通过使用B族亚基金属氧化物如二氧化钛或二氧化锆作为催化剂将乙醇胺（优选二乙醇胺）转化为三亚乙基二胺或1,4-双（2-羟乙基）哌嗪，或二者通过热分解。 此外，还发现，通过使用相同类型的催化剂通过热解，可以高收率地将1,4-双（2-羟乙基）哌嗪和N-（2-羟乙基）哌嗪转化成三亚乙基二胺。 当使用乙醇胺作为原料和IV-B族金属氧化物作为催化剂时，该方法通常导致三亚乙基二胺和1,4-双（2-羟乙基）哌嗪的共同生产，后者可以回收并用作 用于生产另外的三亚乙基二胺的原料，通过循环到相同的反应器或作为另外的热解反应器的原料。

    Abstract: A process for selectively preparing alpha-olefins having from 2 to about 22 carbon atoms by contacting a gaseous mixture containing carbon monoxide and hydrogen with an iron titanate-alkali metal hydroxide catalyst at reaction conditions correlated so as to favor the formation of a substantial proportion of such alpha-olefin product.

    Abstract: Monocarboxylic acids or esters thereof are reduced to aldehydes using hydrogen and a vanadium catalyst. For example, meta-phenoxybenzoic acid can be effectively converted to meta-phenoxybenzaldehyde in a vapor phase process using hydrogen as the carrier gas/reductant and a catalyst composed at least initially of vanadium pentoxide, either supported or unsupported.

    Abstract: Aromatic amines are alkylated by reaction with an alcohol in the presence of a Group V-B metal oxide alkylation catalyst, preferably a major proportion of a Group V-B metal oxide such as V.sub.2 O.sub.5 in combination with a minor proportion of an A-subgroup metal oxide such as SnO.sub.2, so that alkylation of the aromatic amine occurs. Under most reaction conditions a considerable portion of the alcohol alkylating agent such as ethanol not consumed in the alkylation reaction passes through the reaction zone undecomposed and thus can be readily recovered for recycle or other use.
