Disclosed is a method for removing residue from a surface comprising: contacting the surface with a composition comprising at least one unsaturated fluorinated hydrocarbon selected from the group consisting of compounds having the formula E- or Z—R
1
CH═CHR
2
, wherein R
1
and R
2
are, independently, C
1
to C
6
perfluoroalkyl groups, or C
1
to C
6
hydrofluoroalkyl groups, and recovering the surface from the composition.
本发明公开了一种从表面去除残留物的方法,包括:将表面与包含至少一种不饱和
氟化碳化合物的组合物接触,所述不饱和
氟化碳化合物选择自具有E-或Z- R1CH═CHR2公式的化合物组,其中R1和R2分别是C1到C6的
全氟烷基或C1到C6的氢氟烷基,然后从组合物中回收表面。
