How to translate “critical introduction of water” well

Critical introduction of water: It is essential to add some water； Control of whatever comes after the comma. In general, what this sentence means is that the amount of water used in the production of ethyl acetate must be strictly controlled; an appropriate amount of water has to be added at certain stages of the reaction, and this has indeed always been a technical challenge. I’ve never seen a grammatical structure like are has been; I hope someone knowledgeable can analyze it for me……

Controlling the amount of water in the process, as well as ensuring precise control over the introduction of water at various stages of the production process for ethyl acetate, has always been a persistent issue. Precise control over the introduction of water is essential; controlling the amount of water present in the process and strictly regulating its introduction at each step of ethyl acetate production is a problem that continues to exist. Control of ......has been a constant issue, with control encompassing what follows and serving as the subject

Controlling the amount of water during the process, as well as strictly regulating the introduction of water at each step of the ethyl acetate production process, has always been an issue. The term “strictly regulate” was added here, I guess. Would it be better to translate “critical introduction of water” as “the critical point of water’s introduction”? . For reference only: Controlling the amount of water during the process, as well as determining the critical point at which water is introduced at various stages of the ethyl acetate production process, is an issue that has persisted throughout. There shouldn’t be such a grammar structure; it’s possible that the sentence being translated isn’t complete

critical introduction of water: the degree to which water is added

In my opinion, the amount of water added throughout the entire process, as well as the timing of its addition (at which stage), have long been key areas of research. The entire process consists of many stages; thus, even if the same amount of water is added throughout the process, but at different stages, the quality of the final product will still vary.

I agree with rhinocao’s paraphrase; it’s very clear. But I can’t give you extra points, haha. I’ll owe you that one – remember to give it to me next time :lol

Controlling the total amount of water in the process and the critical amount of water that can be introduced at different stages of the ethyl acetate reaction is a long-term challenge. To explain, esterification occurs when acetic acid and ethanol are used as reactants to produce ethyl acetate and water. This is a reversible reaction, and in order to drive the reaction forward, the water produced must be removed promptly.

‘Strict control’ is preferred for the translation, as ‘critical’ already implies ‘key’. This post was last edited by olivetree on 2009-3-19 08:35.]

In summary, \"critical introduction of water\" can be translated as: 1. Critical introduction of water; 2. Strict control of water introduction; 3. The importance of water introduction. Thus, the entire sentence can be expressed as: 1. In the production of ethyl acetate, the control of water volume and the critical introduction of water in certain stages are common topics of discussion. 2. In the production of ethyl acetate, controlling the amount of water and strictly regulating its introduction in certain stages is a common issue. 3. In the production of ethyl acetate, the control of water volume and the importance of water introduction in certain stages are commonly discussed topics. It seems that the second and third ones are pretty good, while the first one is a bit abstract. Those who agree don’t need to reply; just give everyone some extra points O(∩_∩)O. . .
