求翻译：而更难的是不知道这个反应在哪种条件下得到目标产物，同时原料在热条件下的不稳定性带来的问题是不能在加热的条件下促进反应的进行。是什么意思？

The more difficult is not aware of this reaction under conditions in which the target product, while material in the hot conditions, the instability problem caused by the condition can not be heated to promote reaction.

But it is much more difficult to do not know that this response under conditions in which the target product, and at the same time raw materials in thermal conditions brought about by the instability problems are not in the heated response under conditions of promotion.

But more difficult not to know which kind of condition this response does obtain the goal product under, simultaneously raw material brings under hot condition instability the question cannot promote response march under the heating condition.

And even more difficult is not to know the reaction in the target product under which conditions, and also raw materials under thermal conditions brought by the instability of the questions is not under heating conditions for response.

And even more difficult is not to know the reaction in the target product under which conditions, and also raw materials under thermal conditions brought by the instability of the questions is not under heating conditions for response.
