摘要
合成了四氯合锰(Ⅱ)酸正十烷铵(C10Mn)和四氯合钴(Ⅱ)酸正十烷铵(C10Co)两种物质,进行了元素分析,并用DSC,IR对它们进行了研究.发现存在一个固-固相变,且有较高的焓变值和熵变值(△H=35~40kJ·mol-1,△S=110~120J·mol-1·K-1),在较高的温度下具有化学稳定性,因此,C10Mn,C10Co可作为贮热物质.
The his (n-Decylammonium) tetrachlorometallates(Ⅱ) (C10M,M=Cu,Zn,Cd,Hg,Mn,Fe,Co,Ni) which are one kind of potential thermal storage material. In this paper, (n-C_(10)H_(21)NH_3 )_2MnCl_4 and (n-C_(10)H_(21)NH_3 )_2CoCl_4 were synthesized, elemental analysis was carried out. The solid-solid phase transitions forC10M (M = Mn, Co) were studied using DSC, IR. The kind of solid-solid phasetransitions were observed. The enthalpies and entropies are higher (△H= 35~40kJ· mol ̄(-1), △S = 110 ~ 120 J·mol ̄(-1)· K ̄(-1), they are chemically stable even atmoderaterly high temparatures, so that C10Mn and C10Co are potential thermal energy storage materials.
