Title
(EN) HEAT CARRIER COMPOSITION
(FR) COMPOSITION DE VECTEUR THERMIQUE
(JA) 熱媒体組成物
Abstract
(EN) A heat carrier composition which comprises water, a glycol, an alcohol, or a glycol ether as a major ingredient and has high buffering ability in a practical pH range of 6 to 10 even in long-term use. It is characterized by containing a pH buffer which comprises an alicyclic compound in which either one of the ring-constituting carbon atoms has, bonded thereto, two substituents which are one or two members selected from carboxy and salts thereof or at least two adjacent carbon atoms each has, bonded thereto, one substituent, these substituents being one or more members selected from carboxy and salts thereof, or which comprises a heterocyclic compound which has been formed from the alicyclic compound by replacing one or more of the ring-constituting carbon atoms with nitrogen or oxygen and in which either one of the ring-constituting atoms has, bonded thereto, two substituents which are one or two members selected from carboxy and salts thereof or at least two adjacent carbon atoms each has, bonded thereto, one substituent, these substituents being one or more members selected from carboxy and salts thereof.
(FR) Cette invention se rapporte à une composition de vecteur thermique qui comprend de l'eau, un glycol, un alcool ou un éther de glycol comme constituant principal et qui possède une capacité d'effet tampon élevée dans une plage de pH pratique comprise entre 6 et 10, même en cas d'utilisation sur une longue période. Cette composition se caractérise en ce qu'elle contient un tampon de pH qui comprend un composé alicyclique dans lequel l'un des atomes de carbone constituant le cycle comporte deux substituants qui lui sont liés et qui sont constitués par un ou deux éléments choisis parmi carboxy ou des sels de carboxy ou au moins deux atomes de carbone adjacents comportant chacun un substituant qui leur est lié et qui est constitué par un ou plusieurs éléments choisis parmi carboxy et des sels de carboxy, ou qui comprend un composé hétérocyclique, que l'on a formé à partir du composé alicyclique en remplaçant un ou plusieurs des atomes de carbone constituant le cycle par de l'azote ou de l'oxygène et dans lequel l'un des atomes constituant le cycle comporte deux substituants qui lui sont liés et qui sont constitués par un ou deux éléments choisis parmi carboxy et des sels de carboxy ou au moins deux atomes de carbone adjacents comportant chacun un substituant qui lui est lié et qui est constitué par un ou plusieurs éléments choisis parmi carboxy et des sels de carboxy.
(JA) 本発明は、水、グリコール類、アルコール類、あるいはグリコールエーテル類を主成分とし、長期間の使用によっても、pH6~10の使用実用域で高い緩衝力を有する熱媒体組成物に関し、環を構成する1つの炭素原子に、カルボキシル基、またはその塩から選ばれる1種若しくは2種が2個結合し、または隣り合う少なくとも2つ以上の炭素原子に、カルボキシル基、またはその塩から選ばれる1種若しくは2種以上がそれぞれ1個結合した脂環式化合物、または、前記脂環式化合物の環を構成する炭素原子のうち、1つまたは2つ以上が窒素または酸素に置き換わった複素環式化合物であって、前記環を構成する1つの原子に、カルボキシル基、またはその塩から選ばれる1種若しくは2種が2個結合し、または隣り合う少なくとも2つ以上の原子に、カルボキシル基、またはその塩から選ばれる1種若しくは2種以上がそれぞれ1個結合した複素環式化合物、からなるpH緩衝剤を含有することを特徴とするものである。
