    • A reduction process for the metallization of the iron content of ferrotitaniferous materials comprising a first reduction step in the range of 600`C to 850`C in an atmosphere of hydrogen so that more than 5% and not more than 50% of the iron content of the ferrotitaniferous material is converted to the metallic state and a second reduction step of heating the product from the first reduction step to at least 950`C in the presence of solid carbonaceous material so that at least 90% of the iron content of the product from the second reduction step is in the metallic state. At least 90% of the iron content of the ferrotitaniferous material is in the trivalent state when it is submitted to the first reduction step.
    • 一种用于金属化含铁材料的铁含量的还原方法,包括在氢气气氛中在600℃至850℃范围内的第一还原步骤,使得铁含量大于5%且不超过50% 的铁素体材料转化为金属状态,第二还原步骤在固体碳质材料的存在下将产物从第一还原步骤加热至至少950℃,使得产物的至少90%的铁含量 从第二还原步骤处于金属状态。 当进行第一还原步骤时,铁基材料的铁含量的至少90%处于三价状态。

    • Process for the synthesis of a compound of formula I (FORMULA) wherein: U and V may be chosen from a range of substituents including hydrogen, halogen, alkyl and alkoxy; R s and R s may be chosen from a range of substituents including hydrogen and alkyl; n is 0, 1 or 2; and W may be chosen from a range of substituents including the group -//c-G which may be a free carboxylic acid or derivative thereof; the process comprising reacting a sulfate ester of formula II, wherein Q is a cation, with a compound of formula III, wherein L is a leaving group (FORMULA) and hydrolysing the sulfate ester formed. Preferably the sulfate ester of formula II is prepared by the oxidation of a phenol of formula IV with a persulfate.
    • 用于合成式I化合物的方法(配方)其中:U和V可以选自包括氢,卤素,烷基和烷氧基的取代基范围; R 1和R 2可以选自包括氢和烷基的取代基的范围; n为0,1或2; 并且W可以从包括可以是游离羧酸或其衍生物的基团-c-G的取代基的范围中选择; 该方法包括使式II的硫酸酯(其中Q是阳离子)与式III化合物反应,其中L是离去基团(式)并水解形成的硫酸酯。 优选地,式II的硫酸酯通过用过硫酸盐氧化式IV的酚来制备。
