Esters having the general formula: ##STR1## where X is a halogen, n is 1-5, Y is an alkyl, ether, ester, or nitro substituent, m is 0-2, Z is an ester linkage --OCO-- or --CO.sub.2 --, R' is a haloalkyl group, and p is 1-3, constitute high density flotation fluids for inertial instruments such as gyroscopes and accelerometers. Synthetic methods are disclosed for production of such fluids from available starting materials.
酯类具有一般式:##STR1##其中X是卤素,n为1-5,Y是烷基,醚,酯或硝基取代基,m为0-2,Z是酯键--OCO--或--CO.sub.2--,R'是卤代烷基团,p为1-3,构成惯性仪器(如陀螺仪和加速度计)的高密度浮选液。公开了从可用起始材料生产这种液体的合成方法。
