    • A process for the preparation of sulphonated phenols of general formula (I) where R1 is hydrogen, a C1-C20 alkyl group which is unsubstituted or substituted by halogen, cyano, hydroxyl, C1-C20 alkoxy, C2-C20 alkoxycarbonyl, acyloxy and/or phenyl which is unsubstituted or substituted by C1-C4 alkyl, C1-C4 alkoxy and/or halogen, R2 is hydrogen, C1-C20 alkyl or benzoyl of general formula (II) where R3 and R4 independently of one another are each hydrogen, halogen, C1-C12 alkyl, C1-C12 alkoxy, C1-C4 haloalkyl, C3-C8 cycloalkyl, C4-C12 cycloalkylalkyl, cyano, hydroxyl, or hydroxyethyl or are each phenoxy, C7-C10 phenylalkyl or phenyl which is unsubstituted or substituted by C1-C4 alkyl, C1-C4 alkoxy and/or halogen, and R5 is hydrogen or the group SO3X where X can be hydrogen, a monovalent metal or a group —N(R6)3, where each of the three radicals R6 can be independently of one another hydrogen, C1-C6 alkyl or C1-C6 hydroxy alkyl, which process comprises reacting a phenol of general formula (III) where R1 and R2 are as defined above, with a halosulphonic acid in a solvent which is a mixture of a C5-C10 aliphatic or cycloaliphatic hydrocarbon and a dialkyl carbonate of general formula (IV) R7—O—CO—O—R8 where R7 and R8 each represent independently a C1-C4 alkyl group

    • A process for the production of liquid meta-rich triaryl phosphate esters having low triphenyl phosphate content and low viscosity comprises (a) an alkylation stage wherein a phenol is reacted with an olefin having 2 to 12 carbon atoms in the presence of a strong acid catalyst to give a reaction product comprising a mixture of meta and para alkylated phenols; and (b) a transalkylation stage wherein the mixture of alkylated phenols from the alkylation stage is heated in the presence of a strong acid catalyst to increase the meta isomer content of the mixture to at least 25% whilst maintaining a phenol level below 22%; and (c) a phosphorylation stage wherein the mixture of alkylated phenols from the transalkylation stage is reacted with a phosphorylating agent; and wherein the strong acid catalyst used in stages (a) and (b) is a Bronsted acid having an acid strength of less than zero. Preferred catalysts are activated clays such as bentonite, montmorillonite or Fullers Earth clay. The alkylation and transalkylation are conducted at temperatures between 100° C. and 200° C., preferable 150° C. and 180° C.

    • A device (1) for dispensing a volatile substance and simultaneously or sequentially dispensing a soluble substance comprising a structure (2, 3, 4) floatable on a liquid (L). The structure includes a first chamber (5) adapted to receive a filling of a first ingredient (A) adapted to release and diffuse a volatile substance, such as a fragrance, as a result of being contacted with the liquid on which the structure is floated. The structure (1) further includes a second chamber (6) adapted to receive a second ingredient, such as a spa product to be dissolved into the liquid. Floating the device (1) on a liquid such as bath water causes the liquid to contact the first (A) and second (B) ingredients, whereby the volatile substance is released from the first ingredient (A) preferably in the form of a vapour or steam, while the second ingredient (B) is dissolved into the liquid. A preferred application is as a bathing implement or a product for toilet hygiene.
    • 一种用于分配挥发性物质并同时或顺序地分配可溶性物质的装置(1),所述可溶性物质包括可浮在液体(L)上的结构(2,3,4)。 该结构包括适于接收第一成分(A)的填充物的第一室(5),该第一成分(A)适于释放和扩散挥发性物质(例如香料),其结果是与结构浮起的液体接触 。 结构(1)还包括适于接收第二成分的第二室(6),所述第二成分例如待溶解于液体中的温泉产品。 将装置(1)在诸如浴水的液体上漂浮导致液体接触第一(A)和第二(B)成分,由此挥发性物质优选以蒸气形式从第一成分(A)中释放出来 或蒸汽,而第二成分(B)溶解在液体中。 优选的应用是洗澡器具或卫生间卫生用品。
