🧼 皂化值估算器（示意）Saponification Value Estimator (Demo)

使用说明与常见问题How-to & FAQ

「皂化值估算器（示意）」是什么？What is the Saponification Value Estimator (Demo) tool?

示意 SV ≈ 56100 / 平均摩尔质量(g/mol)，单位 mg KOH / g 油脂。非实验滴定。本地处理。Demo SV ≈ 56100 / average molar mass (g/mol), in mg KOH per g fat. Not a lab titration. Processed locally.

如何使用「皂化值估算器（示意）」？How do I use the Saponification Value Estimator (Demo) tool?

在「皂化值估算器（示意）」中，填写「平均摩尔质量 g/mol」等参数，结果会随输入实时计算并显示在下方。In the Saponification Value Estimator (Demo): Fill in "Avg molar mass g/mol"; results are recalculated instantly as you type.

皂化值的单位是什么？What units is the saponification value in?

单位是 mg KOH / g 油脂，即皂化 1 g 油脂所需的氢氧化钾毫克数。本页用 SV ≈ 56100 ÷ 平均摩尔质量 做示意（按甘油三酯计时常写作 3 × 56100 ÷ M），实际以滴定测定为准。It is mg KOH per g of fat: the milligrams of potassium hydroxide needed to saponify 1 g. This page uses SV ≈ 56100 ÷ average molar mass as an illustration (for triglycerides it is often written 3 × 56100 ÷ M); real values come from titration.

能举个计算实例吗？Can you show a worked example?

例如在「皂化值估算器（示意）」中填 平均摩尔质量 g/mol = 860，结果区显示：皂化值 SV（示意）：65.2326；ℹ 经验关系，非实验滴定For example, entering Avg molar mass g/mol = 860 in the Saponification Value Estimator (Demo) gives: Saponification value (demo): 65.2326; ℹ Empirical — not a titration

哪些输入会被检查？Which inputs are validated?

「皂化值估算器（示意）」会检查这些输入——「平均摩尔质量 g/mol」：必须填写，须大于 0；绝对值超过 10¹⁵ 的数也会被拒绝。不符合时结果区显示具体提示，不会给出数字。The Saponification Value Estimator (Demo) checks its inputs — "Avg molar mass g/mol": required, must be greater than 0; numbers above 10¹⁵ in absolute value are rejected too. When a value fails, the result area names the problem instead of showing a number.

有哪些选项可以调整？What options can I adjust?

「皂化值估算器（示意）」的设置：「平均摩尔质量 g/mol」默认 860。每次生成结果都按当前设置处理。Settings in the Saponification Value Estimator (Demo) — "Avg molar mass g/mol" default 860. The result always uses the current settings.

计算结果可以用于作业或工程吗？Can I use the results for homework or engineering?

「皂化值估算器（示意）」使用教科书标准公式（公式写在说明和常见问题中），适合学习和估算核对；涉及安全的工程设计请以规范和实测为准。The Saponification Value Estimator (Demo) uses standard textbook formulas (given in the description and FAQ), which is good for learning and checking estimates; for safety-critical engineering follow codes and measured values.

「皂化值估算器（示意）」免费吗？需要注册吗？Is the Saponification Value Estimator (Demo) free? Do I need an account?

「皂化值估算器（示意）」完全免费，无需注册或安装，打开网页即可使用，手机和电脑都能用；输入的内容只在你的浏览器本地处理。The Saponification Value Estimator (Demo) is completely free with no sign-up or install and works on phones and desktops; what you enter is processed only in your browser.
